Earlier quoted context omitted.
On latest LTS (Ubuntu 20.04 LTS) the apt version is simply a transitional package. It installs the snap for you. It says so on the description directly next to the name: "Transitional package - chromium-browser -> chromium snap" There only for people upgrading, so they are not suddenly surprised seeing their browser gone.
Just seems like an unintended consequences confusing situation. I think a pretty rational policy would to _never_ have an apt package install a snap package. Moving to snap is a breaking change, effectively, so you have to bite the bullet at some point. Mixing your distribution systems with references to each other seems like a recipe for confusion and anger. And it looks like they got the expected outcome.
I mean: clearly some people do care, given that that this thread exists. I think you'll find that they aren't your typical Ubuntu user though.
Users who do care are quite capable of adjusting their configuration, and Ubuntu doesn't get in the way of that (configure apt not to install snapd ever, and it won't).
This is only an issue for users who want to push their political opinions on to other Ubuntu users.
