According to a MacRumors report, warning third party developers to keep quiet no matter what has become the latest fashion in Cupertino:

"THE INFORMATION CONTAINED IN THIS MESSAGE IS UNDER NON-DISCLOSURE," reads the alleged header on the rejection letters.

Apple is known as a company who praises secrecy above all. Third party developers already know that they’re forbidden to share programming tips and the likes, but applying the same rules on basic emails is just ridiculous. Who knows, maybe the next Apple letters will feature the image of Achmed the dead terrorist and “Silence! I kill you!” printed on the side.

In the meantime, Google made sure developers know that the newly announced Android Market will feature none of the chains adopted by Apple. One should wonder just how many developers will dump the iPhone projects and join the other side…
