Canonical couldn't afford the maintenance costs for it. On Ubuntu distributions it's either the snap or you have to create some weird frankendeb aspect by pulling from Debian.
They explained it better than I would.
In other cases, I don't think of a case where apt installs snaps over apt. I think the only priority for the decision choice was based on most recent version. Although this aspect I am slightly unclear.
https://packages.ubuntu.com/focal/chromium-browser
In previous versions of ubuntu, that package would install chromium, as one would expect.
In recent versions of ubuntu, this package is a stub that installs snapd, and then snapd installs chromium.
There is a substantial difference between those two things. Users that try to install chromium through an open package management system are being pushed to Canonical's proprietary store.
> The problem was the decision to change the Ubuntu chromium-browser APT package itself upstream in Ubuntu. Previously, that package would simply install Chromium directly. With the change, it would instead install the Snap package-management tools first and then install the Snap equivalent of the Chromium package — without making it clear to the user what was happening.
I just use the Chrome apt repository from Google which seems simpler all around.
If I understood the issue correctly (and I may very well be mistaken!) the problem Mint has with Canonical is that Ubuntu has "hijacked" (for lack of a better term) some apt packages so that they now actually install snapd and the snap. So you think you're opting out of snap, but when you use apt to install Chromium you end up using snap anyway.
If I understand correctly, this is Mint's main complaint: that Ubuntu seems to be hijacking apt packages with snap.
