And this is how people are, they don't care that they are a danger to the whole internet and them being knocked off is a service to the world. What they care about is their stupid little gimmicky toy.
How people really are is that they don't know what the Internet is so they don't know that their "stupid little gimmicky toy" could possibly be a problem because of some distant and unknown infrastructure issue. It's not a deliberate decision to cause harm, and it's not selfish.
What you think is a "gimmicky toy" may be a security cam they use to keep track of the house while they're gone because they've had issues before. It certainly is NOT something that was sold with a big warning notice that attaching it to the network in their house, behind a cable router that stops everything else from getting in, will cause death and destruction, or problems of any kind to anyone. They certainly did NOT say "fuck you" to any idea of trouble and forge ahead maliciously.
And I'd hate to think that maybe they are thinking that YOUR use of the Internet is for "gimmicky toys" like "why do you need to run your own mail server when Gmail does it for free"?
So, maybe notch the venom down a bit and accept that the problem is not the fault of the people who buy the devices and use them as instructed. People don't need to be, and shouldn't have to be, leet haxor neckbeards with in-depth knowledge of the Internet to use a network-connected device. This is why the idea of having white-hat hackers brick the devices is so tragically wrong. As soon as they start doing that to protect their turf they lose any ethical high ground because they are hurting innocent people and not the ones who produced the faulty devices.
But they'll all call the manufacturer and complain, right? Probably not. They'll take the thing back to the store they bought it from (also not network experts) and get a new one. When it stops working again, they'll get their money back. They won't search out the manufacturer, and are unlikely to find who actually built and programmed it anyway considering it is probably a Chinese company to start with. For example, I have some internet power switches that I caught sending data off to China. Don't know who, and I have no idea who built them. I know the store I bought them from. That's where the trail to the culprits ends.
