Industrial espionage is as old as industry. It got porcelain and tea out of China and is, in fact, the reason the UK was able to grow tea as early as it was.
It isn't nice, but business isn't nice.

I'm not defending industrial espionage, I'm merely pointing out that treating it as a grave and horrible thing is at odds with how important it's been historically.
There are some interesting jurisdictional issues here regarding outright legality of such info and if there is a duty to act by a US corporate officer who is offered such info that is known or suspected to be stolen. If the info theft takes place in the US then all sorts of laws apply (as, for example, Uber is likely to experience in the near future) but if the theft took place outside the US I wonder if the Foreign Corrupt Practices Act makes such a purchase illegal and failure to report a potential crime? I think the Economic Espionage Act only covers theft that goes from US to some other country, but I am curious if the FCPA covers things coming in the opposite direction?
