The Mac App Store was released in January 2011 and it marked the beginning of a great new distribution channel. Even though it lacked some bells and whistles, the developer community was hopeful the problems would be addressed in due course. Unfortunately, it has been years and there's no evidence that the core issues would be addressed in the future, at all. When notable developers are abandoning your platform, cannot do the right thing for their customers and are delaying their MAS submission, something is very, very broken. I believe that the inaction is harmful to the whole Mac community, affecting consumers and developers alike.
Let me make it absolutely clear why I'm writing this. First and foremost, it's because I deeply care about the Mac platform and its future, it pains me to see developers abandoning it. The Mac App Store can be so much better, it can sustain businesses and foster an ecosystem that values and rewards innovation and high quality software. But if you talk to developers behind the scenes or explore the Mac App Store, you'll find something completely different.
