I'm done with Ubuntu
Snaps. I hate them.
They sound great in theory, but the poor implementation and heavy-handed push by Canonical has been a mess.
Snaps auto-update by default. Great for security1, but horrible for users who want to control what their personal computer is doing.
Snaps get forced upon users as more and more system components are forcibly switched from Debian-based packages to Snaps, which breaks compatibility, functionality and introduces a lot of new issues. You can upgrade your Ubuntu installation and then discover that your browser is now contained within a Snap, the desktop shortcut for it doesn’t work and your government ID card does not work for logging in to your bank any longer.
Snaps also destroy productivity. A colleague was struggling to get any work done because the desktop environment on their Ubuntu installation was flashing certain UI elements, being unresponsive and blocking them from doing any work. Apparently the whole GNOME desktop environment is a Snap now, and that lead to issues.
