Same here. What especially irritated me was that even though I installed the .deb firefox and followed the directions to disable snap firefox, occasionally Ubuntu went ahead and reinstalled snap firefox for me.
Ubuntu was great, until Unity debacle, when I switched to Mint DE. Few years later I returned to an Unity free Ubuntu just to be welcomed with snaps and Ubuntu pro.
When I first returned to Linux several years ago I started with Ubuntu, since it was the only distro I had used. I got confused when I installed Firefox and other apps via apt but instead got snap versions. This (very miniscule) gripe is enough of a reason for me to not recommend Ubuntu to new users anymore.
It's not a miniscule gripe tho. Snap is still broken for many users, and relying on it for something as critical as a web browser is asking for trouble. Experimental technologies like snap should be opt-in for users who are willing to deal with the issues they create. Do they really expect a novice to see firefox's filepicker not behaving correctly, and think "Aha, an XDG desktop portal issue! Let me drop everything I'm doing and go troubleshoot that" ? Ubuntu is meant to be linux for normies, they don't have the time or the knowledge to deal with snap.
Exactly that same, really. There were a few things I did that I liked about Ubuntu, like the tray icon extension, but otherwise its nearly identical minus snaps.
