What she did was simply providing good, solid advice on handling security for a stolen i-Device. If she'd just left out that one comment about working for a company that likes to talk about fruit, they probably wouldn't even have a leg to stand on to threaten her over this.
Unfortunately, she's right. The "old Apple" would have reviewed such a thing in context and decided it was accurate information and helpful information, and did the company no harm. The "new Apple" is no longer the dream of a couple of computer geeks (Jobs and Woz), and is a fully established corporate giant.
IMO, this is really no different than things like Paramount going after Star Trek fans for making fan-fiction based on the original TV series and movies. It's clearly only helping boost popularity of their intellectual property and does no harm to the original works. Yet their legal team can't stand the fact, "Someone referenced it without our written permission!"
