I’ve used ubuntu on and off for years. They have a history of questionable choices. Like making users opt out of Amazon searches. Or using unity. or abandoning unity. The most recent thing that made me switch was forcing snap packages on me, which would then be annoying with updates. I switched to debian stable with gnome and flatpak, and haven’t missed anything about ubuntu since.

It’s still a fine distro. The Amazon thing was the only egregious problem IMO
