AFAIK it’s a system to let Linux software bundle all of it’s dependencies up with it so it just works in a self contained way that doesn’t care about what else is and isn’t installed.

Advantages is that they are more reliable and user friendly than traditional approaches to Linux software installation.

Disadvantages are that they have bigger footprints where you might have the same dependencies I dependently installed for each app rather than as a single installation that they all utilise and that they need to be updated individually (as part of the flatpak.) IE if basically every app uses the same dependency and it turns out to have a huge security hole, under normal Linux software the developer would patch it, you’d update it and the hole would be filled. With Flatpaks you need each individual Flatpak developer to update the version used by their Flatpak and for you to update all those Flatpaks before the hole is plugged. I think I remember they run in some kind of sandbox to mitigate this though.

It had nothing to do with From Software but Elden Ring actually ran better on Linux than on any other platform shortly after release (there was a silly bug that affected performance on all platforms that Valve fixed within Proton.)

Do you spend $70 on your wired headphones though? Or are you comparing the durability of cheap crap wired headphones to decent value budget wireless headphones? I have both a pair of Soundcore wireless headphones and a couple of pairs of wired headphones at home that all cost around the same amount and I’m certain I could smash the Soundcore headphones into tiny pieces using the wired ones and the wired ones would still work fine.
