Does this mean that if I distribute one of my applications through the Appstore, I'm legally required to distribute all of my applications that way?
If so, no thanks. I'm perfectly happy to distribute one app through Amazon's store as an experiment, but there's no way I'm going to sign an open-ended agreement to distribute everything at prices set by Amazon.
If they want every app I write, they would need to earn that through good sales and a lack of shenanigans.
