I believe the "non-literal copying" thing simply refers to the insight gained from the R&D time he spent on Occulus while still an employee of Zenimax. 90% of HN members know that this deep understanding is FAR, FAR, FAR more valuable than blindly copying over code.

It was this deep understanding that made Occulus valuable and it was seemingly funded on Zenimax's time and dime.

Perhaps it's not an issue, but it's not like Carmack learned stuff as an employee. He has been the principle architect of the graphics engine for every product he's worked on for the last 20 years. How do you take that out of your head when you change companies but stay in the same field?
