Because a lot of people have multiple drives. I have 2tb of storage across 4 drives. I want to use all of my drives, not just one. This is a very common workflow. Linux has never truly supported it.

I’ve not once seen a software store app (besides something like steam) ask me where to install stuff. Discover, Software Manager, etc. They all just install stuff, typically from the official repos but maybe from flatpak but none of them actually let you change where to install something.

Once Linux figures out a better way to install apps to other drive without causing the user to figure out complex systems it will start closing the gap.

Eh, don’t gate keep. You can be a nerd in very many things and honestly a lot of nerds still use chrome and windows because that’s what works. I use Firefox daily and it breaks a lot of sites. I can’t even log into patreon with disabling firefoxs Cross site blocking because I use Google oauth to log in.
