Twitter is an important reputational vehicle in several scenes. In crypto it is one of the best methods to reach as many as possible "leaders".

CZ also apologized on Twitter after fully understanding what he contributed to (with 22.5). In scenes such as the (Internet) startup world and cryptotwitter, that is seen as a public apology and an absolutely necessity to save face and move forward.

Lastly, CZ is an expert tweeter and fully aware of and skilled in social "tweet protocol". He even used #onwards as a stand-alone, closing tag to his apology. That was not a request nor a desire, that was “topic closed”.

exactly, Twitter is pro Bitcoin as well, so it's like a safe haven mostly....some censorship tho is happening but it seems better than other platforms for sure, Crypto Twitter is a big community, and one place where all the crypto tribes are all located.
