Could you quote....oh.... any of these people being "upset"? Here's an older thread on it:

I don't see a single "upset" person. It's curious. You actually posted this in that thread at post #34, and it's a response to someone who was joking about it. You didn't quote a single "upset" person, there or here. But then, Trumpist baiting does lie on dishonesty; dumber is better because the sheer stupidity of the lie makes it more likely to annoy a liberal, thereby "pwning the libtards" or whatever you call it now.

I think it would be hilarious if he goes all in and lets people post whatever the **** they want. Twitter would crash and burn because, as it turns out, people don't actually want their social media messaging service to be 8chan with a bunch of extra nazis, porn, and nazi porn.
My bet is he'll do little things like add an edit button/window, etc., but not really radically change it. Or if he does radically change it, it will be more to his own business ends. Then we'll get to watch them run around declaring that Musk saved "free speech", not that the term means anything at all divorced from the 1st.
