It doesn't matter what they do. Even if they put 110% into new manufacturing processes, they'd never catch up. Dump your stock and laugh at anyone buying it.
If you like XMPP: Matrix has terrible metadata issues and centralization issues and is funded by a pro-Israel VC funds.
If you like Matrix: XMPP is old, outdated software with broken, fragmented encryption schemes, broken group chats, zero leadership and a community going in 8 different directions at once
Too heavy and bloated, and too centralized in its design philosophy, not to mention big capital flowing through Matrix from Israel and the issues with metadata making it a privacy disaster.
I get your blogger's concern over OMEMO versions being out of whack and their encryption choices being all over the place, but other than it being somewhat of a mess, I don't see how it devalues the service as much as he thinks. (a bit melodramatic imo) I've yet to meet someome whos client can't decode my messages or mine theirs and I've never heard of any successful hack, but maybe maybe.
Half of a foot in nostalgia, another foot in insane possibilities, hobbies and tech, a hand on my family and their goings on and another hand on paying my car off and planning for my aging mother's death and handling the eventual fallout that will ensue.
Mexico actually sounds kinda brilliant, but who seems important. OVH has servers in Mexico, but I can imagine some hosters would get the Feds on the line and go "sure, here's his data".
The enemy of my enemy is my friend, and they have zero say over what I do, only what they do. China could demand and scream and bitch all they want over an encrypted set of programs and you'd never have to care, move to another domain and provider and copy-paste. Lock it down, only use it with encryption and let the wolves huff and puff until they're blue in the face.
Is this an older one? I say that not because it looks worse, just a bit... looser, like the designs aren't as pinned-down. 2006?
