Until the 6th of November 2023 when they—in their words—moved to a different repository and to the AGPL license. In reality, the Foundation did not know this was coming, and a huge support net was pulled away under their feet.

Surprising considering that two of the four Foundation guardians (at the time the Foundation had no board) were Element co-founders

Now, and I can't stress this enough, I really don't think many people at the foundation want this. But with Element sort of just pushing whatever they need in their client and nothing else, I doubt anyone would even be able to get anything implemented in Element to notify Matrix.org users akin to what Thunderbird or KDE started doing in their respective products.

Again surprising seeing as how the Matrix Foundation members I communicate with/am in rooms with about Matrix have suggested the exact opposite sentiment.

This article is all conjecture, but stated as fact.
