Useful summary. If it’s correct that Matrix is analogous to Bluesky (and perhaps Signal too, or possibly Ubuntu), and that the purer alternative is XMPP, then I’m taking that as confirmation that Matrix is what we need.
Bluesky, with its evilcorp backers with $$$ on the line, has far superior UX to the fediverse and is therefore an order of magnitude more popular. A world where Matrix takes off in a similar way is IMO much better for the cause of software freedom than a continuation of the present one where some pure but unusable version of XMPP putters along with almost no users for decade after decade.









Sure but you’ll never have anyone to talk to except a few unusually principled eccentrics with tech skills. Between “XMPP forever” and evil big tech, taking a more pragmatic attitude might result in freer software for more people.
