I agree with all their goals. I just don't see what it will do about the really wicked moderation problems for which they spent so much time castigating the current platforms. Sure, their revocable ocap system would help with direct harassment, but that's not the really tricky, toxic problem. In particular, more private communities (which, granted, were not invented by this project, just hopefully made easier) probably make disinformation worse.
I also object to their implicit equivocation on "context", using it in their problem statement in reference to evaluating toxicity of a phrase, i.e. roughly linguistic context, and in their demo to refer to a social context for the purpose of defining an identity. These are not remotely the same thing. I doubt this was an intentional obfuscation, but they should have been more careful. "Context" is possibly even more abstract than "love", even more so in a "context" including discussions of computer science and linguistics.
