yikes... I'm conflicted. Not a huge fan of Torba, first of all. I checked out Gab a few times, and while I think intentions were good, there is a lot of hateful stuff there. That said, Gab as a platform and app doesn't itself promote hate, so I'm not sure I agree with removing it. That would be like removing Telegram because terrorists have been found to use it.
Much of it depends how public it is. For instance something like whisper needs to remove nudity/hate speech else they'll be kicked off iOS/playstore. But, you can still send it directly without issue.
I'm kind of curious why we can't have an uncensored platform that represents both sides. Is it because good people prefer censorship?
