I mean, I agree that we should both promote and support self-hosting, but it does not at all follow that what happened to KiwiFarms was in any way an injustice or a cautionary tale about the horrors of centralized power. If the ability to self-host came, without exception, at the cost of being able to prevent groups like KiwiFarms from bullying, harassing and abusing people, then it would not be worth it. Fortunately, that's not the case! We can have a middle ground, where people who treat each other with respect and dignity can self-host without fear, and people who abuse the system to actively harm others can be taken offline. This is a feature, not a bug.
