That would be a somewhat valid argument if Snaps "just worked" any better than Flatpaks. That has not been my experience.
Given the choice between an open standard and a proprietary one, the proprietary one damn well better have meaningful technological advantages. I don't see that with Snaps. All I see is a company pouring effort into a system whose only value is that they are pouring effort into it. They should put that effort into something better.
Granted, it's been a few years since I used Ubuntu and Snaps. Perhaps things have improved. It was nothing but headaches for me. A curse upon whoever decided to package apps that obviously require full file system access as Snaps. "User-friendly", indeed.
From an enterprise/server perspective, when what you're really paying for is first-party support, I guess Snaps make more sense. But again, that effort could be put toward something more useful.
