"Take issue with" is vague. Is someone at a company allowed to think, "Dude, you don't talk about Fight Club"? Is that too extreme a reaction? Or are you talking about the legal department filing a lawsuit. Or something in between?
I don't think it's fair to expect Steve Jobs to hop in his helicopter and track down Joe Moreno so that he can high-five the guy for writing something that got on the front page of Hacker News.
It was in part a response to your suggestion that the author might be toeing the line of an NDA violation. The idea that a company would make you sign an NDA prohibiting you from discussing the development methodologies in use is a bit ridiculous to me. (Not that I don't believe that it could happen, but it's not a company I'd want to work for.)
Also, the "because you don't want future collaborators and employers thinking you're a Chatty Cathy who's going to tell everyone about your secret sauce" bit rubbed me the wrong way. I mean... really? I feel like that rates high on the unwarranted paranoia scale.
