I think the biggest impact that the protest has had was to reveal Reddit’s true colours, and to therefore split the user base into two groups: the people that give a shit, and those that don’t.
IMO, it’s the people that give a shit that made Reddit a good place to be in the first place and created the attraction for everyone else. I also have a feeling that the GivvaShittas^tm^ are the bunch that are moving to the Fediverse en-masse and I’m happy to be coming with them.
