>The Brits ... now have to enter an ID to use websites like Twitter, Bluesky, Discord, YouTube, Spotify, and potentially even Wikipedia.
I'm a Brit and have had to enter nothing to access any of those and don't intend entering an ID. There isn't a legal requirement to even have an ID in the UK.
Those that give up liberty for safety deserve neither.
We have a constitution that grants among other things, freedom of speech. They, well, don't.
