> They could finally give the desktop the app store it deserves

IMO the the package managers for most linux distros are better than either mobile app store. There is also flathub and the snap store. Macs of course have the apple app store, and homebrew is fairly prevalent as well. Even windows has AppGet and unofficial package managers like chocolatey. Maybe none of these are what the author thinks desktop "deserves", but if so, then what would be? And why would GitHub be any better at it than any of its tried and tested predecessors
