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.
No surprise to me. Canonical has been headed down this path since they started losing popularity parity with flatpak. Seems like they’re pushing for vendor lock-in.
