But, for several reasons is a much worse experience for people with a large number of followers, especially if they are from a marginalized group.
Everyone should get off X, but I find it hard to recommend any replacement. Threads and Bluesky have problems, but they might work better than Mastodon for some people or organizations.
I read a story of someone that contributed to a BSD project, including fixes over some period of time, but later they ended up having to use a proprietary UNIX for work, that included their code, in a an intermediate, buggy state, but they were legally forbidden from applying their own bug fixes!
At the very least the GPL guarantees that if I am ever downstream of myself, I has fix my own damn mistakes and don't have to suffer them.
I am still willing to contribute to BSD stuff, but vastly prefer something like the AGPLv3.
