The Apple Developer Agreement (on their website when signing up for a developer account) says: "Apple reserves the right, at its discretion, to modify this Agreement, including any rules and policies at any time." And also: "You agree to follow Apple's Guidelines For Using Apple Trademarks and Copyrights as published on Apple's website at www.apple.com/legal/guidelinesfor3rdparties.html ("Guidelines") and as may be modified from time to time." If I buy a Mac with OS X, it comes with Xcode, correct? In that case what does the license agreement for Xcode say? Does it contain the clauses above, or anything similar? If anyone wants to post a copy of the license agreement here, that would be helpful, but I'm not sure if copyright would allow that.
