SDK NDA.... Really?

so i keep seeing articles (http://www.latimes.com/technology/la-fi-apple25-2008aug25,0,2200545.story) discussing iPhone Developers worried they'll get sued for discussing anything about the iPhone SDK and development, "even with friends." uh oh...

i haven't read any accounts of actual Apple lawsuits, or even cease-and-desists/threats. so is this just Apple/iPhone haters posing as iPhone developers, making an anti-Apple stink about nothing, just to get their hate on? or publishers/writers, who aren't ready to actually publish their iPhone Dev books, drumming up publicity?
