Yea it didn't make a lot of sense to me either. I mean if Cardiff's lawyer was basically instructing Cameron to make false statements, and potentially commit perjury, why did they need her at all? Why not just pull some existing Cardiff engineers and get them to do it, since getting someone who already has a job and is loyal to teh company would probably be easier. By the way everytime I hear Cameron talk she sounds like Cobie Smulders.
From what I can remember from a documentary I watched like 10 years ago, the real way the IBM PC was cloned was a lot more air tight legally, since they basically did like a double blind research study, with one group being like the bearded dude and figuring out what the IBM does, then another group, completely separate from the first figuring out how to make a computer that can do the exact same thing.
