It really is annoying that they don't make it opt-in instead. They've got plenty of users; I can't imagine they need to be collecting usage statistics from everyone.

I'm curious what would happen if a moderate-size country (say, Belgium) were to pass a law saying that telemetry must be opt-in. I bet it would convince everyone to just be universal opt-in for simplicity's sake.

That said, I bet it's still nothing compared to the level of data collection that a typical website does these days.
