You're misunderstanding the purpose of the article. The author is examining the general tendency for hierarchical organisations to require require moral submission on the part of people who work within them.

Snowden at al are given as recent, specific examples of people who claim that their "moral compass" requires them to take action. It is entirely possible to disagree with them (and you clearly do) but its much more difficult to argue that dissent based on moral conviction should never be permitted under any circumstances.

Then again, maybe you're just trolling and I've wasted my time.
