Google is politically very very left. I'm guessing that someone at Google may have browsed these apps, decided they didn't like what they saw, and pressured to have the apps banned. Obviously they can't do that to large players like Facebook, but small apps, they can easily crush, and nobody's going to do anything about it.
Image if Google decided to just block certain websites on Chrome, or if big tech got domain registrars to drop 4chan, or whatever humor websites they don't find amusing.
