The problem with snap isn’t that it’s useless, it’s that it’s garbage. Snaps are just plain worse in every way, compared to other packaging formats. They impact boot time A LOT… like A LOT A LOT on a hard drive, use a ton of space, are slow to launch unless you use like tricks or what not to speed up consequent launches after the 1st one, the store backend is proprietary and poorly moderated, the store is slow and unresponsive, and cannonnical is pulling some real micro$oft-esk shit to try and force them on users… Stuff like aliasing apt commands to snap, disallowing ubuntu spins to ship flatpak by default, etc…
The only redeeming quality that snaps have is that you can run CLI/server programs as a snap, and even then, just use docker lmao.
