I spent my time fighting AppImages until Canonical started to force Snap on me. I hated Snap so bad it forced me to switch distros. Now I appreciate Flatpak as a result and I don’t find AppImages all that bad, either. Also, I haven’t found myself in dependency-hell nor have I crashed my distro from unofficial Repos in well over a decade.
-It’s a long way of saying It works for me and it’s not Snap.
You’re not wrong, but these days the number of members of the public that truly cares (to point of taking action) about privacy is an extreme minority.
