So my theory with the Twitter thing is this. They want to kill Nitter/similar, they want to kill scrapers using logins to bypass it, but most importantly Twitter wants to reduce user loss by locking users in.
They've been nudging people with this since locking NSFW to logins and then locking out Nitter from it. Want to look at that dank furry porn? Sorry bud. Gotta log in.
They're now applying the same thing to people like my dad who would doomscroll Twitter without an account and see what their favorite TV celebs and news guys were saying about Trump/Desantis/trans kids. The idea is that Joe Normie will make an account to view this. He won't use the fediverse because Rachel Maddow or Tucker or NPR (depending on who he voted for) is not on the fediverse.
When Twitter rolls it back they won't do shit. They'll go back.
