Mir, Unity, now Snap. Ubuntu has a track record of wanting to go it alone.
But, I'm all for competition, long may it continue. The only real negative here is that some apps will only release Snaps, others will only release Flatpaks and people will end up having to just revert to copr/AUR like before.
Choosing a distro is basically choosing a DE and package manager these days anyway - a single unified packaging format that works everywhere is more frustrating than an alternative DE or windowing system.
