In the first year of the Mac App Store, before sandboxing, I bought as much as I could from it. As a customer, the convenience was so great that I even repurchased a few apps that I already owned just to have the App Store updates and reinstallation convenience. And, most importantly, when an app was available both in and out of the Mac App Store, I always bought the App Store version, even if it was more expensive. But now, 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. I agree whole-heartedly with Marco on this. When the Mac App Store first came out, I began buying everything on it, and why not? It was great! I could sit down at any of my 4 Macs and instantly have access (well, with download times maybe not quite instantly - but easily) to all of my OS X software. I began to snug apps who weren't on the Mac App Store unless I absolutely needed them, such as SuperDuper!. And then, Apple had to rain on its own parade with Sandboxing and Entitlements. Now, I've had to purchase newer versions of several apps off of the Mac App Store because they've pulled out due to Apple's onerous restrictions that break core functionality of their apps. Apps that have been hampered by the Mac App Store that I rely on or are very popular: Textexpander, Alfred (which you cannot get from the MAS if you want to add-on their 'Powerpack' functionality due to the inability for in-app purchases), Hazel, SuperDuper!, Reflection, all of Atlassian's apps, Postbox. Myself, Manton Reece, Daniel Jalkut and others have been keeping a running list of articles on Pinboard about apps that have pulled out or have had updates rejected due to Sanboxing shenanigans. Someone at Apple who has the power to step in and reverse this poor direction Apple is currently taking with the Mac App Store had better do so soon, otherwise they are going to either doom the Mac App Store from being a long term success or lose years of progress while they recover from this bad decision years from now.
