I run Gentoo, which has a telemetry use flag. This will enable telemetry for a number of packages.
I hate telemetry on non-FOSS software like Windows, but is there real harm in doing it with FOSS software? I like to think I’d be helping the devs create better software.
It’s all about transparency and giving you the choice to opt in. When it comes to KDE, you can clearly see what is being sent to help the developers. The same cannot be said for Windows and closed source software.
I absolutely love the KDE approach and I always enable telemetry for FOSS apps if I can see what exactly is being sent. Hell, I wouldn’t even mind some opt out telemetry if I could see what data the app sends back “home”. That’s, obviously, if the data sent doesn’t violate my privacy significantly
