I’d say Executables (for all their risks) make it pretty easy for less savy users to get apps not immediately made available to them, given there are definite security issues.
But I will be fair that I think Linux’s flatpaks are helping a bit with making apps more available without worrying about the distro. Plus proton/wine lets users grab some of the useful exe’s from windows.
It’s improving I do agree, but it’s something that will hopefully keep improving.
