I'm probably really out of the loop, but what is matrix.org?
Looks like an open source slack clone?
Why do they have >5 million user accounts? Is that everybody who uses that chat tool?
It describes not just Matrix in the French state (like in the title), it also covers the Matrix 1.0 release and what they want to do with the project (e.g. they eventually want to shut down matrix.org once the ecosystem is mature).
and the animation at the bottom of the matrix.org homepage was quite helpful for me
