It is my understanding that a lot of EU governments are setting up their own matrix servers.
Matrix shows me as active (green dot) when I have the client open but there's no way to override that. At least none that I found. I'm a bit surprised all these big governmental clients didn't ask for such a feature :)
But sorry that they are not contributing. That's pretty bad tbh.
That they publicly use it at all is great though, as it likely helps shift the Overton window of what's normal, and what fits standard useage of Matrix-Synapse
