Leave it to an Apple fanboy to paint choice as a bad thing.

Sideloading apps and alternative app stores onto an Android device is (and has been since Android's inception) almost completely painless once you click past the scary warning saying "hey, Google hasn't scanned this app, make sure you know what you're doing", and I've yet to meet a single non-enthusiast Android user who even knows that. I'd wager that not even grandmas are going to be fooled by something claiming to be the app store that isn't the app store (considering there'd be two app stores on their phone), and even if they are, big flashing warnings that say "Hey, this isn't us" are well within Apple's capabilities.

The fact of the matter is that people don't find APK downloads and alternative app stores without explicitly seeking them out, and that's more than enough to keep away the people who are so technologically illiterate they need to be saved from themselves.
