I love this comment section. Perfect balance of people actually trying to discuss and people getting pissy because their answer can be the only right one.
I don't know shit but when I try and picture it happening in my head I can only see A being correct, think Doctor Strange portals. When he moves a portal the person comes out stationary
It's kinda one size fits all solution. It allows Devs to build their package one way and have it on pretty much every distro, which is a major sticking point for Linux apps. I don't see why you would use a flatpaks if your distro has the software already though. I use flatpaks alot less now that I've moved to endeavour from fedora. The AUR is a godsend.
Also flatpak doesn't add to dependency hell, the dependencies it installs are also flatpaks and are completely separate from the system. Recently the arch package of steam simply stopped launching proton games for some reason, I thought I messed something up on my system so I rolled to an old btrfs snapshot and it still didn't work. However the flatpak version of steam just works.
