It still irks me that AppImages (the unambiguously superior choice) are not more successful than Flatpak or Snap solely because Linux users (in their characteristic laziness) are only used to getting their software from monolith stores and repositories.

At least in the case of Snap, I felt that Canonical itself played a role in making it dominant in Ubuntu so that they could control the ecosystem.

Personally I use AppImage whenever it's an option. It's the closest we get to Windows and MacOS executable applications

I love AppImages, but Flatpak tried to go way beyond - centralized updates, sandboxing/permissions system, package once, run on many distributions...

Getting software from repositories is not just laziness, you automatically get updates and the software from repos is supposed to work with your distro, that apparently is not always true with AppImages.
