The shitty thing isn’t phoning home, the shitty thing is doing what’s not described on the label.
If a piece of software says “this will do X if you run it” and then it does X then I don’t see the complaint (yes I realize lots of software uses dark patterns or doesn’t say what it does, especially windows, but _in principle_ I don’t think anonymous telemetry with good clear opt out/in is evil).
Because it's not their fucking computer!
Nothing about this is necessary.
Nothing here is "blurry".
