Reddit acts horrible right now. First they basically destroy third-party apps instead of making their own app better, then they threaten and replace moderators on their subs and just do whatever they want.
If Reddit were a country it would be a dictatorship with an idiot as its leader.
Personally I support the protest by just not visiting Reddit anymore, request my data and hopefully delete my account there.
In the end a lot of users will not care but I hope they are the ones that do not contribute to Reddit and just consume which would lead to a slow death for Reddit. And in the short term there hopefully is enough chaos and bad decisions to reach the press and hurt Reddit that way.
