Or unless the capacity of you harddisk is limited, filling up with huge snap packages.

Or you need something that is broken by snap. I helped a user after thunderbird after an upgrade could no longer open PDF-s in okular. It turned out that the thunderbird dpkg had been replaced with a snap and I spent quite some time trying getting it to work, filed bug reports, etc, before giving up and installing from Mozilla until I replace it all with Debian.
