Exactly! And if you really need any sort of "telemetry" to get the data that you need, then do what so many other FOSS software I've seen with any sort of "phone home features" does, and simply ask the user during the first run if it's okay to send <such and such data> for development purposes. (Also, a toggle in the preferences is always nice, too, so that I can enable such a feature on days I'm feeling particularly helpful, and still easily disable it on days I'm feeling like there's no need for my software to be sending data anywhere outside my network.) It's not uncommon for me to approve such features when I'm dealing with software I trust, and when I'm thoroughly informed of exactly what data they're collecting and why. If I see a list of reasonable data points and it's not too intrusive or overreaching (and if I can examine the data before it's sent) then I'm quite often okay with it (again, with software I already trust for other reasons).
