Please note that these folks seem a little confused about the the takedown of a single Matrix server. Matrix is an open source encrypted protocol, and there are multiple sets of Matrix clients (Element most popular) and open source server sw, many servers, and multiple matrix networks. This takedown seems unrelated to matrix.org

@dragosr Apparently it's a different, proprietary thing The article should really clarify that https://en.m.wikipedia.org/wiki/Matrix_app
@cy @annika It's still probably Matrix under the hood.
For those unfamiliar with it, there are loads of Matrix networks, private, public networks.
I was trying to match the screenshots with known Matrix clients to verify, problem is there are too many now. Think we can rule out text only ones but, with multiple mobile and desktop OS versions each that's a lot to check:
Element
Element X
FluffyChat
Nheko
Cinny
Fractal
Quaternion
gomuks
Hydrogen
NeoChat
SchildiChat
Ement.el
Tammy
iamb
chatty
@dragosr @cy Dunno, maybe. Europol's clarification to The Register was, "The Matrix protocol (matrix.org) is by no means connected to the Matrix secured communication service that was targeted in OTF Continental." https://www.theregister.com/2024/12/04/eurocop_crack_matrix/
