However, a thing I try to remember and wish others would as well is simply this: Canonical is a company. Their goal is to make money. They are not out to create the ultimate free as in freedom Linux distribution.
This does (to my mind) not make them evil, and ESPECIALLY doesn’t make the folks who work there evil. It makes them participants in the great horrible game that is Capitalism, and expecting anything else from them is going to lead to heartache, as you’ve seen.
If you want a Linux distro that shares your preferences and won’t try to jam snaps down your throat, you might consider giving Debian a whirl as many others have.
Continuing to ride the Ubuntu train and raging against the dying of the light when it continues chugging in the direction it’s been headed for YEARS seems … futile :)
