Debian, RedHat and Firefox do have telemetry. Not a lot, but enough to prove it is possible to do it in a way that doesn't piss most people off. Naturally the way they collect it is open source, it's largely de-identified, and because it open source you verify it's de-identified enough for you. And if it isn't you can turn it off. So it's possible to do well, where "well" means gets you the data you without pissing off the users. Most proprietary don't bother to do it well for whatever reason. But they should be careful: it a big factor in diving things like Home Assistant, Linux Desktop and now this, apparently.
