The matrix.org post-mortem... as written by the attacker.
Ouch:
@fribbledom I stopped wanting to be involved with matrix when I realized its leadership was behaving like a tech company and the architecture of the protocol reflected that. It already suffers from a mountain of technical debt and they don't even have the resources to address that to move forward with stabilization. Too much, too fragile, too fast.
@shaderphantom
Any suggestions for a replacement usable by non-geeks?
@skyguy i don't think "for non-geeks" is a useful way to categorize communications technology. the reason "non-geeks" use stuff like slack is being of concerted marketing efforts, not because they are functionally better.
matrix is attempting to be a competitor to slack. but slack was designed to centralize and replace IRC. they even pulled embrace, extend, extinguish by taking down their IRC protocol support a while back.
if i had a choice, the "replacement" would be IRC or XMPP.
