Defaults matter a lot, and snaps are the default in Ubuntu.

The topic is not whether snaps are avoidable or not, but the Ubuntu is going downhill. And snaps are purported to be part of that downhill, which would be Ubuntu's NIH syndrome. As far as I know, Ubuntu's only successful development is Ubuntu itself - the other projects have all failed over the years, and snap, while ongoing, is not winning any popularity contests either.
