Amazon works if you're looking to buy recently manufactured cheap stuff from China and pay a little more to get it faster than AliExpress/Temu/etc., or to not have to get multiple when you only want one. But what's the alternative to buy and sell things with other people or independent (not local to you) stores? Especially older stuff? Especially when you're looking for an auction format or to take/make offers? The Amazon selling platform is FAR more complicated than ebay, to the point many people are not willing (/able) to use it, and offers less features. And - even after all these years - it's awful for anything other than books. The search is horrible, they do nothing about sellers spamming keywords in titles, and they sometimes show you things the algorithm deems similar instead of the thing you actually want; so if you're looking for something specific, if it will be shown to you or not at any specific time is a crapshoot.

I've tried Facebook Marketplace and from both sides (seller and buyer) I got tons of scammers (that I didn't fall for), people that couldn't read, people only willing to do local pickup (making scams far more dangerous), and people who said they would buy/sell and then never showed up. So ebay is the only place I have found to buy/sell things like old sewing machines and parts, old knitting machines and parts, (for both of those, the recently manufactured replacements often don't actually work, or don't fit by just a slight amount - but enough to make them incompatible or to mess up the machine, sometimes don't work as well as the older ones when they do work, and nearly always aren't as durable) old computer parts, and old video games (I'd worry what GameStop would do to that category if they bought it...). And since Joann's shut down - and because Amazon bough fabric.com and then shut it down a few years ago - ebay has been a godsend for buying fabric, as many independent fabric stores (the ones that managed to not be killed by Joanns) won't go through the hassle of running their own website. Although some people sell fabric on Etsy, it tends to be considerably higher priced than on ebay. (And while vintage stuff is sold on Etsy, it tends to be only toys and clothing, none of the machine parts nor computer parts, very few video games, and obviously there's no auctions.) Thrift stores have become overpriced, and you're limited to what happens to be in your local thrift stores. Except for Goodwill (if you even consider that a thrift store) where you're limited to what they decide to put on their auction site - which has exorbitant shipping and they don't test anything (they might, at most, sometimes see if a sewing machine powers on, but that doesn't tell you if it actually works and is useless if you need a specific working part), don't bother to research if all the parts are included, aren't detailed in the pictures and description, and don't let you ask questions clarifying any of those things, making it useless for the majority of things I use ebay for.

I've been using ebay since it became ebay, and I've never even wanted to do a return. Everything has always been as described and pictured, unlike on Amazon. Maybe that's luck, or maybe it has something to do with Amazon's limits on item descriptions and photographs, how they group items together (what you call complicated, I would probably call detailed), and how they seem to do nothing about defective or inaccurately described products. From the selling side, I've had ONE person complain about something I sold on ebay, and they didn't even ask for a return - I don't know what their point was really, as they just listed every flaw that I described and photographed in the listing as if they were complaining, and I replied, "You're complaining that it's exactly as described?" and they said "No, I'm not complaining, I just expected it to be different." So I don't know, maybe they only looked at the first picture and didn't read. But, they left a positive review.
So one problem - that was not even a problem and was likely the result of the buyer not reading - in 29 years on ebay, vs on Amazon I have had to take advantage of those free and easy returns many times. Although actually the last few times I tried to do a "free and easy" return it ended up not being so easy because the places I had previously used were no longer drop off partners, so I had to find a new place. And the most recent time - a few weeks ago I had to return a bike tire that just barely didn't fit the size wheel it was supposed to be for, meaning that it looks like it's on there but at some random point the tube explodes (which is obviously dangerous) - there wasn't even actually a free option available, because there is no longer a drop off that is accessible to me, so I had to pay to have either Amazon or UPS pick it up. Free and easy returns are nice (when they're actually free and easy) but it's easier and free-er to not get a product that is defective, dangerous, or not as described in the first place.

Anyway all that to say, if you have actual alternatives to ebay I'd love to hear them, because no, Amazon and AliExpress are not replacements.

Do away with homework, bring back study hall/add it to all grades, and give students the option to put on noise-canceling headphones and work independently. And give them access to optional practice material.
So basically have them do the same things they would do for homework, but mostly during school hours. Students that need even more practice still have the option of practicing outside of school.

I have not even seen a standard telephone in at least 20 years. But difficulty using something patented by someone who was anti-deaf-people would be a point in favor of my argument that the suffering comes from hearing people being discriminatory and exclusionary, not against it.

They suffer from getting surprised by things a hearing person would hear coming long before ...

Arguable, some deaf people have enhanced other senses, and I am frequently surprised by things I should have heard...

Or get an extreme example: neighbours are looking strange at them, because they are loud in bed, and do not notice themselves.

Some deaf people can feel when they are making sounds. But either way, any suffering from that is not caused by being born deaf, it is caused by a social stigma about being loud in bed.

A guy shouting at you: "damn idiot, can you not move out of the way, are you deaf??!!"

Not having to hear such a person seems like a benefit to me.

somebody born deaf will never be able to enjoy Beethoven's Ode to Joy

There are ways to enjoy music other than hearing it. Beethoven is an ironic example since he went deaf (though I don't know enough about him to know if Ode to Joy was composed before or after that).
But, I understand your overall point. However, there are aspects to life that a deaf person experiences, that hearing people do not. To by default choose to deny your child the chance to experience life THAT way, assumes that hearing life is the best life. Many deaf people would argue against that.
I don't know what the right choice is, nor what choice I would make for my child in that position.

I can see how being born hearing and then going deaf causes suffering, but I don't see how being born deaf does. Seems to me that the suffering there comes from hearing people being discriminatory and exclusionary. Your attitude is part of the problem.

Great, but that doesn't answer my question at all.

The number of bugs isn't reduced by a project being closed source.

So if the pace of claims is so large that you can't fix them all, what do you do? Neither no longer giving an incentive to discover flaws, nor no longer accepting claims, reduces the number of flaws.

What's faster, fixes with a few select people working on them or fixes with anyone in the world able to work on them?

If a person isn't going to follow the rules of not exploiting vulnerabilities, they also aren't going to follow the rule of not breaking into closed code to find vulnerabilities.

since they killed the "download & transfer via USB" option last year.

The the "download & transfer via USB" option on the Amazon website, I mean.

this just means you can't purchase, borrow, or download new content for those devices through Amazon. And this was already the case for all the Kindles that don't have wifi, since they killed the "download & transfer via USB" option last year.

I'm sure the thought is that people will buy new Kindles - and I'm sure many people will, especially with the confusing way this news is being shared. But pre-2012 Kindles still work, just with no reason to buy books from Amazon. Seems stupid to me to turn away all the people that want to keep buying books but don't want to buy a new Kindle (and really there's several reasons to not, some of which might be accessibility issues for some people; for example they replaced the text-to-speech feature with a pitiful, cumbersome screen reader after they bought Audible), but I guess they're counting on people not being able to figure out they can keep using them.

So, what, they just leave in security vulnerability bugs that anyone can now easily find using AI?

That's interesting - I also know someone that gravitates towards and shares AI slop daily, that has mental disabilities. Worst part is, lately if we tell him it's AI (because he'll share stuff like "10 unexplained videos" and directly ask what we think it is, or ask why something happened in a video, or how something was done) he gets defensive, saying things like "not everything is AI!" He can't understand that because he's engaging with AI slop, the algorithm shows him more AI slop, so his feed is all AI slop now.

That's some ridiculous circular logic. If we let fewer unsafe drivers drive, not driving will be safer. And even people that truly need a car to get to work don't need a car with only one person in it; they can simply get into a vehicle that SOMEONE ELSE IS DRIVING.

They can be just as productive WITH SOMEONE ELSE DRIVING THEM. It will just be less convenient and perhaps embarrassing (not that not driving is inconvenient and embarrassing, but people that drive everywhere often feel it is). Countless people that CAN'T drive manage.
