But its not about just how it started. Snap was more focused on phones and servers, not on desktop in the beginning. And there were not much, because Snap was usable over the following years (like Flatpak). Canonical could see how the entire rest of the Linux communities and distributions adopted Flatpak and could have switched to it. But contrary to it, Canonical was very pushy about Snap. So my argument is, Canonical should have dropped Snap early when they still could (just like they did with Mir in example). But they didn't.
Obviously now its a different situation, but you were talking about the beginning in this reply.
