Tldr at bottom

Your link is not working for me. That domain has a blog where the author talks about their Revolt account being terminated (this was over two years ago), but the drama seems to be about one lead contributor banning the author across several servers they moderate. The author gives no explanation for what they actually got banned for and only includes a few dm screenshots that don't really explain anything. The author links (incorrectly formatted) to this callout post where the author of that complains that the hobby programmers who maintain Revolt in their free time are hobby programmers who maintain Revolt in their free time (as opposed to unpaid developers who dedicate their life to the project). The author literally complains about who they describe as a teenager "playing video games such as Beat Saber VR, Minecraft, Fortnite, Among Us, and Valorant instead of focusing on the product". Brother it's not a product you're not paying for anything. Skimming through the rest of the takedown post, this is your generic right winger "I'm being cancelled for my beliefs, so much for the tolerant left" nonsense that losers do when people stop giving them the time of day they feel they're owed by others. kate.pet referencing that callout post does not lend credibility to their own claims, I must say.

Tldr there was internet drama two or three years ago that affected like two people, both of whom include screenshots so closely cropped that I feel like one extra message above or below each screenshot would change the context of what's being said. I would hardly call this a controversy. If you want to avoid it that's your prerogative, but to me this hardly seems worth writing off the whole project over.
