geek writes "According to Marco Arment, the creator of Instapaper, Apple may be in trouble with developers. According to Arment, the new sandboxing guidelines from Apple are pushing developers away in droves. 'I've lost all confidence that the apps I buy in the App Store today will still be there next month or next year. The advantages of buying from the App Store are mostly gone now. My confidence in the App Store, as a customer, has evaporated. Next time I buy an app that’s available both in and out of the Store, I’ll probably choose to buy it directly from the vendor. And nearly everyone who’s been burned by sandboxing exclusions — not just the affected apps’ developers, but all of their customers — will make the same choice with their future purchases. To most of these customers, the App Store is no longer a reliable place to buy software.' Arment also comments on the 'our way or the highway' attitude Apple often takes in these situations and how it may be backfiring this time around."
