Yep. My business recently ported (well, _I_ ported) our main product from Windows to OSX. After reading up a bit on the App Store and the Apple developer ecosystem, we decided to completely avoid all of it and distribute our software on our own. Having a third party dictate major business decisions in this manner is absurd and ought to be avoided when possible. It's not clear what we'll do if Apple takes steps to force developers to join up and use the App Store (which isn't outside the realm of possibility).
