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.
The most popular non-Canonical derivatives, Linux Mint and POP OS, have both totally rejected and vocally criticize Canonical’s bullshit, Snap or otherwise. This isn’t going to make the fall in line, this is going to make them finally get serious about ditching Ununtu and switching directly to the upstream Debian base.
