The former Twitter leadership was very clear about what sort of content would be his. And is was based entirely on the type of content ahead of time. Critiquing this sort of content policy is like saying that newspapers should not be allowed to have clear standard for what is publishable in classified ads.
All claims of "I'm being oppressed" by Twitter policies have been absolutely ridiculous, and discrediting to supposed free speech advocate/absolutist positions.
Similarly discrediting is the silence on Musk's attacks on the free web and attempts at censorship of specific disprefeerred news outlets.
We all see what gets fought ago and what is not faught against, and the answer is clears the right to attack and intimidate groups with threatening behavior is defending, but actual censorship of reasonable discourse is tolerated.
