Apple Extends Non-Disclosure to App Store Rejection Letters
Apparently, Apple has now started labeling their rejection letters with Non-Disclosure (NDA) warnings:
THE INFORMATION CONTAINED IN THIS MESSAGE IS UNDER NON-DISCLOSUREReaders should note that Apple's developer correspondence may have already been covered by the original NDA, but Apple is now making it clear.
In contrast to Apple's approval process for the App Store, the newly announced Android Market claims an entirely unrestricted free-for-all model. Early concerns about that model question how inappropriate, spam, or malicious material may be filtered. It seems that the efforts to prevent issues such as bandwidth abuse have been shifted to the carrier who has implemented caps for the 3G data plans at 1GB per month:
If your total data usage in any billing cycle is more than 1GB, your data throughput for the remainder of that cycle may be reduced to 50 kbps or less.
