Isn't that the purpose though of Ubuntu though?
No, because back in the day when Ubuntu was "Linux for human beings" you could literally feel that in almost every aspect of it, from the ease of its installation to its icon theme and system sounds to its help pages. It was their "selling" point - it made Linux friendly and reachable for many people, as it did for you and me.
It's been more than 15 years since I used Ubuntu but from that point I really could feel that what @merci3@lemmy.world says is true - it no longer offered any real benefit compared to Fedora, Solus, Mint or whatever distro targeted at people getting into Linux. You won't find many people saying that Ubuntu really stands out from their similars about something. It just became another option, forgot what was "Ubuntu" about (remember the Amazon ads scandal?) and seem to be really stubborn into impose to the community their way of doing things (snaps, mir...). Or tell me with a serious face how the snap thing makes the life easier of someone wanting to install a deb.
It's correct what you say - as many other distros, they have done a great amount of work over the years and most of us are grateful to it because we could get into Linux thanks to it, nobody can deny that. It's just that said work no longer seems the case nor they seem really interested about that.
