People's complaints about Twitter moderation aren't about the law, they're about governments being able to indirectly make de facto, unconstitutional law through either informal demands and threats to, or overly chummy and profitable relationships with, media companies. It's not hard to figure out why media and payment consolidation and monopolies are allowed/encouraged. They're ideal for government.
I don't understand how orchestrated bans across media companies and payment processors can be allowed when price-fixing isn't. They're behaving as trusts.
Can we nuke Facebook on the way too ?
It twitter abandons the European market, people will use something else.
Yes, and then be disconnected from the rest of the world.
Or even worse - no substitute service would even spring up, giving a strong signal that people don't actually need the service FB/Twitter offer at all!
They only stand to loose for exiting a market as a protest.
