And a lot of the complaints about both are very generalized. "Flatpack is bad package management technology" tells you very little about what is wrong with it.
Systemd was such an improvement over the existing speghetti for folks selling / supporting linux that it was a pretty clear takeoff.
Flatpack seems a bit more focused than snaps. The usability issues with snaps kind of surprising given ubuntu has usually had a good user focus. One thing, Fedora has their silverblue / ostree type distribution initiative, which may reduce their use case for using things like flatpack for printer subsystems etc (snaps seem more flexible). I moved off linux desktop a year ago though so not at all current unfortunatly.
