With snap they can release the package a single time, and it can be used across all of their releases. I think this is the main point of snap. Being able to use it across other systemd distros is just a bonus.
Flatpak is not a solution for packaging a large portion of the types of software Canonical packages with snap, such as database servers, kernels and containerisation software like lxd.
But if flatpak doesn’t meet the widest use case of snap, are they really describing flatpak?
