I think pre-Musk, there was no one person who controlled content and a group of executives likely determined what was acceptable/unacceptable. Warnings were given to violators before removing them. And it was free to be a verified person of fame.
Now under Musk he wants people to pay to say they are a certain famous person (easily exploited, as proven) and people have already been suspended/restricted instantly. Dictatorship.
IMO, Twitter should just be a place you can speak your mind (without hate speech, market manipulation, threats or dangerous misinformation). It's where I find out when artists I like release new music, see firsthand video of incidents occurring around the world, and join in on the worldwide conversations about what's happening on this funky mudball we call Earth.
