Most of the people I’ve introduced to Linux don’t even use the shell. Beginner-friendly Linux distros are perfectly usable without ever touching a terminal, just as most people use Windows without ever touching PowerShell (or worse, the Registry Editor).

That’s not the worst possible scenario, I’d love to see the Snap Store completely replaced by decentralized FOSS alternatives. Any scenario in which the Snap Store takes market share from decentralized FOSS alternatives is considerably worse.

Also, who said I wouldn’t use proprietary apps? I refuse to use Snap because Flatpak and other FOSS application packaging solutions that aren’t locked to a store controlled by a single for-profit company already serve my needs. I don’t have any objection to using proprietary apps that don’t have alternatives that meet my needs.

Silly whataboutism. When there are multiple Linux package management solutions to choose from that are functional, decentralized, and fully FOSS, including ones that work across distros, switching to the proprietary Canonical-controlled Snap Store is moving backward for no good reason.

The Snap Store server is completely proprietary and fully controlled by Canonical.

I don’t think that’s the case. The v0.19.0 release notes say:

Instance Blocks for Users

Users can now block instances. Similar to community blocks, it means that any posts from communities which are hosted on that instance are hidden. However the block doesn’t affect users from the blocked instance, their posts and comments can still be seen normally in other communities.
