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.
That's a very serious allegation to make without citing any source.
Still collects some user data
Someone has already pointed out, no data is collected unless the user opts in. But, my question is what's wrong with collecting anonyomized telemetry about most used hardware and most used/unused software features? It helps developers make better decisions.
Because it's a shit company which seems to employ more lawyers than devs. Their lawyers routinely go after emulators, which hurts game preservation. They also go after fan projects a lot, which hurts the community.
