I always felt like Canonical had a big problem with going all-in on something they thought was neat (the Unity desktop, Mir, that thing where phones and desktops were supposed to merge, now Snaps) and letting everything else stagnate, then getting the thing they were working on to the point where it was almost good, then dumping it and going after the next shiny thing.

But yeah these days I think things like Pop!OS and Mint are better Ubuntus than Ubuntu is.
