I'm inclined to agree with you, and it sounds more like "Muh business is like the government and you go to jail!".
That being said, just how bendy are the laws on corporate espionage, theft of information, etc? The problem isn't that this is basically a civil dispute between employer and employee, it's that Congress is all too willing to pass laws that criminalize these kinds of disputes and in the employer's favor.
This makes it very convenient for corporations to use the FBI as their private enforcement arm and makes threats of criminal prosecution plausible if not real, especially if the employer does a good job with keeping up with their political subscriptions, er, contributions.
