Put yourself in the maintainers' shoes — would you be happy to idly stand by when you know your service is being used to actively harm others' lives? [^1] Perhaps you would, and if so, I would be interested in hearing your view.
Let's also not forget that, even if you disagree with sr.ht's stance, you can still freely benefit from the thousands of hours of work put into SourceHut by self-hosting it for whatever project you want. Therefore, I think the maintainers' work should be applauded regardless of your take on this post.
