Ubuntu is a shell of what it once was. They're not going to make Snap optional, they need to justify its existence by releasing everything as snaps with no alternative so you have to use it.
Or, just use Debian if you like Debian-style distros?
Or, wait for it - this is gonna sound a bit radical but hear me out - give Fedora a try? Flatpak instead and unlike Debian Stable has packages from this century
