Seeing that there are so many different types of non-disclosure agreement forms and legal paperwork that forbids people from mentioning about work or proprietary intellectual property, it's rather ironic to see technology blogs reporting "leaked" information. The question people should really ask is, "How 'leaked' is it?"
If I were a multi-billion dollar company about to release a product, would I sit idly by as an employee decided to "leak" my IP and potentially give away secrets which competitors could easily glean? If these people are not being sued for their actions, I can only assume these "leaks" were intended. And if they were intended, they aren't "leaks".
Maybe "thematically-infused press releases"?
