Only it's not free, it's included with the subscription cost that airtel customers are already paying. If it was free it would be available for everyone.

Addressable does not mean accessible.
IPv6 has link-local addresses which are unroutable outside of the local segment. Plus firewalls and VLANs exist so you can limit access however you want.

This is a _LOT_ better than the typical device that connects to someone else's hosted server that you have absolutely no control over.

The same is true of pretty much any animal... Dogs can kill, cows can kill etc. Even small animals are potentially dangerous although you're more likely to be able to fight them off.

The problem is operating on a blacklist approach...
One chemical gets a bad name and there's a campaign against it, so it gets replaced with something that hasn't attracted so much negative publicity yet. The replacements are often worse, or the side effects are not so well known and once use becomes widespread the side effects are found to be worse.

You've seen this with legislation that pushed vehicles from gasoline to diesel, reducing co2 while increasing other emissions.
You've seen this with food where fat/salt/sugar (that we've been consuming for thousands of years and which are perfectly safe and even needed in moderate quantities) has been demonised, leading to worse replacements where new negative side effects are regularly emerging.
Micro plastics, coolants and various other things are also getting worse.

It depends how bad the problem you're suffering with is...
If the choice is between "100% agonising death" and "a drug that has a 1% chance of curing you or 99% change of agonising death" many sane people would choose the latter.

Or mandate prominent ratings displayed on products - similar to the energy ratings.

None of the cinemas around here have such high quality equipment. Maybe they do elsewhere in the world but then catching a flight to see a movie that's better than what i can see at home isn't really a sound economic proposition.

Exactly this... Nowadays everyone already has a portable device capable of reading up to date content anytime anyplace. Buying a paper magazine or newspaper from the few places that still sell them and then carrying it around is massively less convenient. The only people doing this are generally the elderly who dont know how to use the newer technology, and obviously those people become fewer every year.

No i have a smaller room so i sit closer, so i have no need for such a large screen.
Plus i can sit in exactly the ideal location for the sound system and screen, whereas most of the theatre audience are sitting outside of the optimal seats.

Also theatre experiences differ significantly. Some of them have much smaller screens, lousy sound systems, dirty, smelly, crowds of kids, uncomfortable seating etc. There isn't a decent one around here, i have to travel a significant distance for a decent theatre experience.

Not really, both wechat and alipay have a tourist card option that you can top up with a foreign debit card. It has a 3% fee i believe but then you can pay for things the same way the locals do.

Modern end user devices are designed that way, as you simply cannot rely on a perimeter to protect portable devices that will be connected to all kinds of public wifi networks that you have absolutely no control over.

You can always add more wires, you can't invent new radio frequencies.

A company will be allocated a /48 or larger, and will allocate /64 blocks to VLANs themselves, so you do have a hierarchy.

It's the same in a lot of places - legacy traffic is through CGNAT unless you pay (sometimes a LOT) extra. If you want any kind of home server you have to do it over v6. Also makes it much easier if you have more than one device since you can access them directly rather than having to mess with non standard ports or proxies etc.

Vodafone are a mixed bag - depends what country you're in. They have v6 in india, portugal, germany etc while in some other countries they don't.

Only if you're relying on perimeter security rather than a zero trust model.

With a perimeter model the printer could be the access vector that gets you behind the perimeter.
