Twitter has taken even greater steps against the same kind of violent messaging in the US itself. How does that fit into your theory about imperialism?
Twitter controlling political discourse in America is not imperialism, just corporatocracy. If Americans would like to live under such a system, so be it. Just keep your frankensteins out of our country please.
It's like as if the users want the tech elite to be the arbiters of their truth, handling 'accidental' banning of users who disagree and allowing the free-for-all manipulation of content that it only approves of (Even when it approves of lies) whilst also claiming to stopping 'disinformation' as so called 'mOdErATioN' whilst breaking their own rules.
These companies will never change and neither are your friends or are on your side.
