A lot of people made the mistake of treating Twitter like a commons and have been burned. My local police force posts all notices about traffic, missing people, foiled crimes, etc., on Twitter out of inertia. That is wholly inappropriate, and wasn't appropriate even when before it become some brain-worm infected oligarch's rhetoric megaphone. The same goes for many organizations, politicians, and so on. It was never the right choice. And the solution to one bad choice isn't to move to the same mistake on some other service. These people and orgs need absolute and complete ownership over their own platform.
Mastodon / ActivityPub seems like it might scratch that itch, but what a bloated sloppy mess that is. The right idea, with the wrong implementation.
Honestly would prefer all these people and places just published RSS feeds.
