Edit2 If I think about it some, the biggest drawback about Threads for me is swapping one egocentric billionaire who is rapidly going off the rails for another who is, for the moment, more stable, but has still accumulated a godawful amount of wealth and power. Mastodon seems like the alternative if you really hate that kind of setup, but... it doesn't seem to have much traction.
