And the combination of those two things means that if you are a big enough, important enough software project, then you can't rely on bug reports or random ragesite comments to tell you when your product is failing. You have to have telemetry. It can't be opt-in because in any scale that matters _opt-anything doesn't exist_.
And if you also care about protecting privacy, then you start walking a burning tightrope.
That's the job.
