Everything you said is true but it’s beside the point, all this app store stuff shouldn’t affect how easy or hard it is to install something the old fashioned way.
I know Firefox is there but I would to have the option to install it and programs like it without some kind of app store.
You mentioned android and it’s a perfect example of what I want, you have a nice app store but you can if you want download any app or anything from a website and it’s just one file that’s easy to install and it won’t update along with everything else or they can often check for updates on their own.
