Wait, isn't in that movie... what was it called... ah ! «Brazil»

That's a bad analogy, more like :

Printing Press <=> The Internet

but

Social Media <=> Some specific forms of (mostly centralized) publishing

Out of all of those, only Instagram is on the list (or I have heard has complied despite not being on it).

You seem to be confusing messaging software and social media ?

Do (the others than Instagram) have an algorithmic feed, or (effectively) do not work without making an account ?

I guess that there's also Discord (that isn't on the list but has still complied) that is in an awkward in-between ?

(IMHO both Instagram and Discord ought to be banned anyway, for everyone, because they're deep web platforms that are owned by Meta/Tencent, and are therefore a threat to the open web and liberal democracy.)

Them being platforms is most of the issue. Protocols (like Mastodon or PeerTube), not platforms.

Logging IP addresses for use by law enforcement started in like 2004.

I remember ISPs and Web cafés complaining quite a lot.

But I guess you mean on the client software side itself ?

Normalizing ID and ID uploading (instead of banning it) is really what makes this bad.

A good law would just have completely banned these platforms from the country. (Even the Canadian Kik, because freeware, therefore closed source, therefore a platform.

EDIT : Looks like it's instead the Australian Kick, The Register had it wrong ? Same deal. (Especially with its owners having a gambling background.))

I wish the EU would be bold enough to do this, especially with Trump's bullying, but I have already been disappointed in the past, despite the situation clearly calling for strong actions like these...

Discord might not be officially included, but they still complied.

«Big Tech» is a bad term to use IMHO, but if you do, why wouldn't it cover Discord(/Tencent) or even Telegram ?

Going to say Nope there....I know a lot of kids using discord, they do not have age checks in Australia.

Seems like it was only newly introduced for Australians wanting to access Discord (not-)servers (and/or channels) declaring themselves 18+ only.

No, about half of them (mostly) aren't : Reddit, YouTube, Twitch...

(That's also not what «walled garden» means. You're thinking about «deep web».)

You say it's a LOT, but it's about the same cost as a much much shorter USB 4.0 cable. (Granted, it also has to be able to carry 240W.)
