Can someone explain in 3 short phrases or less how ActivityPub or another standard actually solves the problems that centralized social media creates?

Best to think about it like email. You can send and receive email to anyone at any domain, if their server is set up for email. We all just happened to centralize ourselves onto Gmail and Google's servers.

Replace email with "social media content" and you have ActivityPub.

Choice of your instance, moderators, and client. It enables smaller, self-policing communities to run a compatible instance with minimal costs.
