I'm genuinely curious how this compares to something like, say, Mastodon. It seems to me like Mastodon actually offers a lot of the same advantages.
It's weird to me how the no-retractions thing is a benefit. Seems like a feature deficit. I can't imagine using twitter without the delete function, if only just to delete botched tweets.
I can think of lots of situations where that's not a good thing. I can't really think of any situations where it's a good thing.
