And that 'truly decentralized option' comes with a problem that will permanently dissuade many serious people from using it — there is no way to prevent imposter accounts. Imposter accounts will be attempted for anyone of significant standing or authority posting anything authoritative (e.g., product or policy announcements) controversial or notable, and with no way to shut them down and maintain an authoritative presence of you, no one of note will even go there, or stay once they encounter the problem. Easier to stay somewhere else like Bluesky or Spoutible where they at least attempt moderation and authentication and declare "Any Mastodon accts purporting to be me are fake.". I've personally spoken to authors/speakers/officials who checked it out after Twitter was sold to Musk, and once they understood the no-authentication-in-principle problem, said "NFW".
