War with who? I’m posting this from Kubuntu and I’d happily agree with you that Snap should fuck off and die. (In particular, the backend being controlled by Canonical makes it objectively bad compared to Flatpak.) Even among people like me who tolerate Snap (for now…), I really don’t think you’re gonna find anybody who actually likes it, let alone enough to champion it.
Can’t start a war when there’s a consensus!
As far as I know, I’ve only installed Flatpaks using the terminal. The most annoying thing about them for me is having to type out the fully-qualified name of the software (e.g.
org.mozilla.firefox
instead of justfirefox
), which is a very terminal-specific issue, LOL!
