It seems obvious to me. Twitter has historically been used by public figures, and especially public institutions like local governments, transit agencies, etc, to make official announcements & statements. Of course having that on a centrally owned social media site was never good, but now with Space Karen making it actively hostile to users (and trying to prevent logged out users from seeing that info), it’s very bad. The sooner Twitter completes its inevitable collapse, the sooner those public figures & institutions will move to a better way to deliver those - Mastodon, RSS, webpages, whatever.

IMO it’s in the public’s best interest for all the holdouts to get out now so we can move on.
