It's a stretch to say that imposing a Stalinist command structure over the kind of programs your computer will run is to make them easier to install and cut down on malware. Apple's operating systems are nearly invulnerable to viruses because the deep infrastructure is cadged from Unix and other open-source places, which are inherently better-built and less vulnerable to viruses. I suppose if everyone ran Linux, viruses targeting it would be more common, but surely part of the reason Apple made this choice was to deliberately cripple the functionality of the device in order to force their customers into the Apple ecosystem and thereby make a big pile of cash.
