In effect, Gatekeeper's user-experience can raise interrogations on its ultimate motive. For instance, when a downloaded application is blocked, no mean of circumvention is suggested. The user is led to believe their action is just wrong. Still, power users will soon know about the left+click+Open one-time override, leaving the security argument somewhat lame. Clearly this feature is a boon for Apple to draw its users towards its store.
Even more controversial is the notion that one must be registered with Apple (and therefore pay, no matter how modestly) to sign their applications so as to make them unobtrusively available. If the mechanism was to spread to other platforms, how could Open Source cope?
Is Gatekeeper compatible with the ideology of Free Software?"
