Some fair points but the move to element x and new authentication wasn't it.
Authentication was a nightmare and the new one standardizes and allows for oidc, better security, etc.
Element was SLOW and standardizing on the rust SDK and moving to element x was the best move. Threads and spaces will come in time but the speed was needed. That and schildichat already has their own x client so it's not like theyre deciding what to do.
Definitely pain points remain but I feel the author just got in too early. I don't blame them for being tired but now I think matrix is finally somewhat near a turning point.
