Wow. I just realized that Unity games already report "telemetry" by phoning home for quite a while. I have serious doubts that this is legal. My main point is, that I have a contract with the game developer/platform where I buy the game. But not with Unity. They have no consent to collect any data from the user.
Thanks greedy Unity CEO for making people look closer at Unity, so they see what a mess this thing really is.
