Matrix have always been suspect.

Disappointed but not surprised.

In short they are saying that if the nation states hadn't opted to use Matrix they would never have bothered developing this Rust version, which only shows that they were never sincere about developing a performant open source version, not to mention their involvement with some suspect Israeli comms companies and the phone home agendas.

Interesting question - will their "nation state" level customers have the right to inspect the source and make changes to it?

Just waiting to have this post flagged.
