It's also about support. You buy one of these, and then 2 months later call up Dell and say the Wifi on laptop is not working, then it can go one of two ways.

If you're running Ubuntu 22.04, then you'd be justified in demanding they support it, and repair/replace as appropriate. If you're running $SomeOtherRandomDistro, then their support team you're dealing with may not have the right tools/processes to test and diagnose the issue. It would, I would argue, be justified for them to reject your support request until you can show it failing in Ubuntu 22.04. Assuming it wasn't something obviously physically wrong with the device.
