Yeah, you're right.

I was focusing on leaks to media/news sites but that's because the Apple memo seemed to focus on that as well (e.g., "The employee who leaked the meeting to a reporter ...", "Instead, people who work for Apple are often targeted by press, analysts and bloggers ...", and so on), although they did specifically mention leaks "in the supply chain" too.

Leaking/selling company information to a competitor or rival is obviously a concern as well but I think this memo is pretty clearly aimed at those who might consider leaking to the press.
