I’ve run Ubuntu Server frequently on VMs for work, but I could kinda go either way on it. The majority of people who have issues with Ubuntu have philosophical differences. I’m inclined to agree for my personal stuff (in principle I’d rather not get my packages from a single source that works on their own whims, in practice I never use anything but Flathub unless I need a package with deeper permissions) primarily because I believe that Linux should be as open as possible. That said, I already mentioned that my principles there only apply to machines I own, so I guess I’m a bit of a hypocrite 😅
