When did you last evaluate a system like Ubuntu? I'd have agreed with you 10, perhaps 5 years ago. But things have changed.

Yes, they are always changing, I know Linux since 1996, use it as part of my work, last time I used a system like Ubuntu was last year, where it failed to work with a GIGABYTE BRIX Mini-PC UEFI firmware when starting from internal SSD, which I eventually gave up after several weeks trying various workarounds.

That's the point.
