That's horrible move from Feynman about credit.

It was also a "horrible" move for the two editor/publishers to claim equal author credit for Feynman's much more extensive creative effort.

In reality, a simple negotiation led to a good decision that made everyone happy.

[It’s worth emphasising that Sands was hugely positive about the lectures and was great friends with Feynman.]
