In part I am curious about how these requests are made; I would expect that the 2 most common kind of request are from law enforcement following public channels/groups, from individual reports of private conversations, and from previous investigations.
That is I imagine requests would be in the shape of "here is a username give us IP and phone number".
It is also relevant to know whether German courts can order to collect this information, it is also relevant that German courts apply German jurisdiction universally (an example there are African war lords convicted of war crimes that have no relation to Germany or German citizens).
Personally I would prefer privacy first companies to focus on lobbying the idea that these kind of court orders are to be used sparingly rather than enter an adversarial arm race with regulators.
