For simple “apps” it is fine, but my computer is not a phone and I don’t use it like one. I mostly don’t want simple apps that have their own little sandbox to play in.

I want full-scale applications that are so big they have to use system libraries to keep their disk size down. I also don’t want them in a sandbox. I want them to have full access to the system to do everything they need to do, I want them to integrate with far-flung parts of the system and other applications too. I only use applications I trust and don’t want them constantly pestering me about configuring permissions and access in just the right ways and opening all the right doors and ports and directories to make them work, I trust them by installing them, they have permission, and the easier they make it to access everything I will inevitably be asking them to access, the happier I am.

My practical concern with distribution methods like AppImage and Flatpak is that now I have to do a lot of extra thinking every time I’m installing anything. To pick how I’m going to install something, I have to solve the matrix of “what kind of distribution method do I prefer for this type of software” combined with “what distribution methods are available for this software” and “what versions are the available distribution methods for this software” and “what distribution method provides the best way for this software to get updates”.

In the olden days, when the distro’s package manager was the only choice, all I had to care about was “is it available in my distro” and the decision tree was complete. I appreciate all the availability of choice that things like AppImage provide, but it doesn’t actually make it easier for me, it just makes it easier for the packager of the software. They’re doing less, but making more work for me, as a user. Distro packages are a lot of work for the maintainer precisely because they at least make an effort to solve many of these issues for the user. The value-add that maintainers provide is real.
