Just glancing at his feed, Elon seems to talk about spam bots, free speech, making the extreme left and extreme right equally unhappy, and shadow banning. Sounds like he wants more fairness and transparency in how Twitter moderates content.
Unfortunately that depends on his personal definitions of "extreme left", "extreme right", and "free speech."
"extreme left" and "extreme right" are pretty widely agreed on by anyone who's not part of one or the other.
If I am on Twitter's Trust and Safety team, I'm sweating bullets today.
They should all be looking for choice B companies. I suspect there will be a mass firing/exodus for anything involving security or feed algorithm teams.
