I am currently only on Linux on my Steam Deck and I do have two RPi’s (though I don’t actively use them) so I don’t have personal current knowledge of differences between Snap, Flatpak, and App Image beyond that A: Snap always brings up lots and lots of hate in comments and B: is from Canonical.
But is it possible that they might choose to use Snap for having more program options due to Ubuntu being such a “mainstream” distro? I know lots and lots of programs do release Flatpaks, but are there more of them or does Snap have more? Real question since I am aware of how heated some threads get with folks being really “fuck Snap” or “it is fine.” Mostly just curious since I am more and more likely to move my main PC to Linux as my main OS after Windows 10 is dead.
I think that your example of the App Store and the Microsoft Store is helpful! I work on both systems at my job fixing computers for consumers. The only thing I dislike about the App Store is that it doesn’t let you install things without first signing in with an Apple ID (the spam levels of pop-up messages trying so freaking hard to make you sign in is infuriating). But the MS Store feels like all the worst parts of the Play Store and really fucks things up if it breaks. I will likely remember your reply the next time I think about Flatpaks and Snaps though. lol
