Blogger Marco Arment says Postbox’s exit from the Mac App Store should sound very familiar to anyone who buys Mac software – the real story being one weve seen a lot since June 1: they tolerated the App Store’s lack of paid upgrade mechanics before, but sandboxing and more accurately, needing to remove important app features because of their incompatibility with the current set of sandboxing entitlements was the last straw.
Arment observes that Apple’s stance seems to be pretty typical of them: comply with the new rules or leave, which usually works for them, but this time, they’ve made a critical strategic error: leaving is often a better option, or the only option, for the affected developers. Many of them have already left, and many more will.
He notes that he’s lost all confidence that apps he buys in the App Store today will still be there next month or next year, which negates most of the advantages of buying from the App Store are mostly gone now, and his confidence has evaporated, deeming the App Store no longer a reliable place to buy software, and in significant danger of becoming an irrelevant, low-traffic flea market where buyers rarely venture for serious purchases.
