Saying Ubuntu has telemetry like Windows is shaky at best. Ubuntu asks you whether you want it, doesn't mandate it for people who don't buy enterprise licenses, and doesn't sneak in new kinds of telemetry when you already disabled what's there.

Saying Ubuntu overrides auto-update settings is just false. If you turn off automatic updates, nothing will automatically update.

Even if Canonical ever become evil, we have distributions and it is open source. You can change any part, a lot of distributions built on top of Ubuntu. For example Google can disable uBlock in Chromium, some would switch to Ungoogled, Iridium, some to Opera, Brave, Vivaldi.

Imagine if Windows, macOS, Google services were easy to fork.
