Platforms of the same nature like Mastodon.social ? Because no.

Actually, internal reports seem to indicate Twitter under Musk complies with much more takedown requests than it did previously, numbers seem to range from 80% to 98%, including requests from countries like China, Ethiopia, Turkey, etc. When people mention censorship by big tech the top three names are Twitter, Facebook, and Google. The only time I know of that twitter fought censorship was when India wanted them to takedown news about farmers’ protests, and Twitter lost in court, probably owing largely to the fact that he cut staff by 80% and ran the company’s finance into the ground by endorsing hate speech.
