The American left has suffered a huge blow losing Twitter as an enabling presence. I don't know for sure, but I suspect Elon Musk is more conservative than most folks think. Surely, he is buying Twitter to combat the assault on balanced discourse in the USA. Obviously, the richest person in the world doesn't need the money.
It is the progressive left that fears the exposure of ideas. It has always been this way. The communist takeovers in Russia and China led to tens of millions of human beings being executed because they were suspected of dissent.
