In a surprise move, Ubuntu developers have agreed to stop shipping Flatpak, preinstalled Flatpak apps, and any plugins needed to install Flatpak apps through a GUI software tool in the default package set across all eight of Ubuntu’s official flavors, as of the upcoming Ubuntu 23.04 release.
Yeah, it definitely does CLI applications better, I think Oracle uses it for some of their system monitoring services on Oracle Cloud for example. At least the snap issue I linked is also still open unlike the issue for better CLI handling for Flatpak which was closed without being fixed and makes the guy who closed it look like an arrogant asshole.
To be honest I don’t really like either of these because they both have big flaws like that, and of the three major “standalone app formats” I prefer AppImage the most simply because I can just download those without needing to install some other daemon first.
