If we’re both working for the common good, then it doesn’t matter whether the game is zero-sum or nonzero-sum in the first place. If everybody’s working for the common good, then there isn’t really much point to game theory at all.

The point is that nonzero-sum does not imply that the rational strategy is to cooperate all the time.

I know that nonzero-sum does not imply that the rational strategy is to cooperate all the time. I would agree with the OP if ey said that it’s sometimes rational to keep secrets. But eir actual recommendation was entirely unconditional. Incidentally, OP also seems to act against the spirit of eir own advice by giving this advice in the first place.
