Ubuntu has long suffered from NIH syndrome, constantly inventing its own non-standard components (snaps, Unity, etc) and trying to make them "win" by forcing them on their own users. Reminds me of Microsoft with its non-standard Internet Explorer, its own non-standard version of Java and others.
The lesson is to use a Community distro, not a Corporate distro. When the distro's goals align with its community's, even a distro based on Ubuntu will usually be better than straight Ubuntu. For example Mint keeps the good things about Ubuntu (in Mint's opinion of course), removes the bad things like Snaps, and adds other features that the community wants that Ubuntu won't (like built-in Flatpak support among other things).
