Most distros let you either opt-in or opt-out of it though. It’s really not as big of a deal as people make it out to be. Besides, the “general” population switching to Linux doesn’t really care about anonymized telemetry.
Discouraging people to not use a certain distro due to its optional and anonymized telemetry, is foolish.
If you have to dig that deep, then it’s probably not worth it digging (for me at least).
