What’s your take on Apple’s Think Secret lawsuit?

Dan Gillmor calls
Apple's lawsuit a case of corporate misbehavior. He thinks Apple is trying to suppress free speech: "I'm not a lawyer, but it seems to me that Apple's only legitimate legal beef is with its employees or contractors who are leaking the information to Think Secret and other rumor sites."

John Gruber doesn't think so: "this is not a case of big bad Apple putting the screws to a little guy." His take is that Apple is trying to
use scare tactics to prevent future leakages. He also notes multiple attempts on the part of Apple to warn Think Secret that they may be treading on thin ice: "If Think Secret wasn't prepared for this, it's because they're foolish, not because they weren't fairly warned."

What's your take? Is Apple abusing its corporate muscle by going after the little guy, or are they justifiably protecting their own interests?
