tbh you’ll likely find yourself better using anything else that isn’t Ubuntu. Debian is cool if you’re okay with your desktop environment being a bit behind (as for apps you can5use flatpaks for the most up to the date, it also is good if you need most app support as it can install .deb) or arch if you want to learn a bit more about how your little penguin lives inside that metal box of yours! Fedora I am not sure as I think they implement or will implement telemetry.

One last thing is that not all telemetry is bad. if you take a look at KDE’s initial prompt for telemetry it is anonymous and is used to simply try and make the DE better
