Couldn’t the same argument be made for any distro? They give you what they put in their repos. If you want a deb package, use the mozillateam PPA (which is built on Canonical’s hardware, same as Mozilla’s snap of it).
the difference is that the folder/package structure for other package manager is open and well known
everyone can host their own i.e. apt, pacman or Flatpak repository with little effort
the required folder/package structure for snaps is no longer open and you cannot change the default snap repository either easily
The package structure for snaps is very much open, as is the API for a snap store. There was for a long time an open source snap store implementation, but it died out due to lack of interest by others in actually hosting their own stores, which to me says a lot about whether people actually want to host their own repo or just want to use it as a way to complain.
IIRC, the issue was that - unless you take steps to explicitly prevent it - Ubuntu would occasionally reinstall the snap version. I don’t remember the details, been a while since I had to dance that dance, but I recall it being one of the things that put me off snap in particular, Ubuntu in general and sparked my search for a different distro.
I’m now on Nobara, a Fedora-based gaming-oriented distro maintained by GloriousEgroll (who also maintains the popular Proton-GE)
Like with any time you’re trying to select a specific source for a package, you need to set apt configuration to prefer that source. It’s standard apt behaviour with a standard way to configure it.
Correct me there, but wasn’t the “select source” thing intended to be about different deb sources?
The issue is that what you expect to be a deb package manager ends up redirecting to snap anyway. It’s not a different source, it’s a different system. If I have to manually take steps to avoid using the distro vendor’s default sources because they just redirect to a system I don’t want to use, I might as well look for a different vendor.
And so I did
