Regimes fall every now and then. Coup attempts happen all the time. I have never seen media or social media ban any Government account over it.
I guess Social Media has a different conscience for when regime change/coup-d'etat happens in say Iraq vs when it happens in USA.
What this has done is set a very bad precedent. The Big Tech is acting like Supranational Powers overriding what Elected Governments can and cannot do. Remember that the transfer of power hasn't completed yet. Trump is still the elected President of USA until 20th of January.
If Big Tech can do this to a sitting elected President, it can do it to anyone else. No Government in the World is safe from Big Tech censorship.
(per 4chan/qanon) it's all false flags. that lady wasn't shot. she threw herself back on to her padded backpack... because "they" knew that if someone "died" then they could quell the uprising. (which is actually pretty insulting to the "revolution" isn't it?)
i spent the day poking around a lot of conspiracy theories and videos and man.. that's one big rabbit hole of mental illness.
But on the subject at hand, I can't imagine a platform that was required to carry Trump's content that I would want to be a part of.
