Ubuntu is a controversial example. Probably better usability than most linux distros, but it collects a lot of data (lots of telemetry, amazon app, etc)
What do you think Ubuntu collects without an explicit option to turn it off, or even having it off by default? Canonical have had a couple of mis-steps in that direction over the years, but the Ubuntu community has pushed back consistently against intrusive measures and Canonical have typically backed down very quickly when they overstepped the mark.
