More importantly, though, I think anything a company says internally should be 100% irrelevant in an antitrust case. It's like the famous advice parents should give their kids when it comes to relationships: "Just ignore everything a potential partner says, and only focus on what they do."
I mean, it's not like corporations need to have any sort of "mens rea" to be found a monopoly abuser. IMO all that should be evaluated are the actual actions a corporation took to stifle competition. I don't really see why internal communications are relevant at all in these trials.
