I think this will lead to outcome that few people cheering for this are anticipating. Musk, Thiel etc. will back an alternative platform that will host JRE, Lex, Jordan Peterson etc. and in the long term it will win due to being less restrictive. Which in the long term is prob a positive thing.
Also even if your prediction is correct, that's "less" restrictive, and still not completely open. There will always be rules because whoever's paying for the service, whether it be advertisers, subscribers, or billionaires, has a list of things they really don't want to hear.
