Who is “they?” One guy? Out of the 10s of thousands of employees? So now we’re thought police?
Well, to be fair I think intent will be a central topic in the court case. Epic is clearly trying to picture Apple's intent negatively, namely enforcing strict control on a platform where they enjoy dominant position to stifle competition. Apple is likely to counter that their primary goal is to protect the users' privacy and security instead of being anti-competitive.
I don't think conclusions can be drawn by only a few emails, but Epic will likely try to dig up multiple instances of such internal discussions and present them to argue that they were not isolated cases but following a pattern.
