BUT, and it's a huge caveat, the ability to choose what I see is not the same thing as moderation. Dorsey makes the usual tech bro mistake of assuming that we can only be harmed by the speech that we see.
That's simply untrue. In my view, a healthy platform on which its members feel safe and allowed to flourish can't afford to host hate speech, period.
Telling Black Twitter, LGBTQ community, etc. etc. to simply filter out the bigots is a failure right off the bat.
