Apple has a bad rap when it comes to the iOS app store being locked down. They control it with an iron fist. One of the main resons I like Android is because they don't lock down the phone to only what they want you to have. Right now a mac can get an app wherever the user pleases. If this changes, I will never buy a mac. If I have to get a mac app from the mac app store than Apple has gone too far.
A Mac is a full-size computer, and you should be able to to what you want with it. Anything else should be against the law. A lock-down is only a little bit more excusable on a smartphone. The Mac App Store is restricted to its iOS counterpart's standards, but I have other choices. The internet is at my disposal. Should Apple make the Mac App Store the only choice for apps... they will have committed suicide.
