Then 99% went with Flatpak, except one, Ubuntu with their own proprietary solution called snap.
It's not the same thing. We have a decent (yeah not perfect, I'll spare commenters the effort of posting that same old tired flatpak rebuttal) cross distro packaging solution, but Canonical always wants to play different and not collaborate with the other standards. So here we are.
In 10 years the "Ubuntu Store" will be a pretty frontend on top of Flatpak just like Gnome Software, and just like every NIH Canonical product made before it.
