Twitter’s new policy is “freedom of speech, but not necessarily freedom of reach” and it seems to be going okay.
You should be able to say what you want but that doesn’t mean that it’ll be able to trend. It also means that Twitter is not in the business of making judgements on what is socially acceptable to say.
Also the new community notes feature has been great for countering misinformation/extremely biased takes. They only appear when a mix of people who have diverse backgrounds have said that they are useful, which I think is pretty balanced.
