I sincerely cannot understand why otherwise normal and thoughtful people/organizations continue to patronize X/Twitter. I literally quit my job as an exec at Twitter when it became clear Musk would take over the company, and the level of ineptitude and noxiousness today has dramatically exceeded what I thought would have been possible at the time.
People and organizations tend to look for signals that others like them are leaving. If those signals get loud enough, you get network effects. But few want to be "first" in their group, so groups stick around.
I've seen the most sustained migration off X in Germany, which is probably no surprise. (See https://bit.ly/eXit where I'm tracking major departures.)
