Defector: never cooperates

Forgiving: always give, even to those who don't cooperate

Tit-for-tat: cooperates by default but does not reward defectors/freeloaders. This often the best strategy.

Interesting how this applies to software licenses.

Permissive licenses are clearly forgiving actors.

Copyleft/protective licenses are a gentler version of tit-for-tat.

I don't recall where or when I read it, but there is a strategy that usually beats Tit-fot-tat.

Tit for tat, but also a small (random) chance of forgiving (giving a break) anyway. I believe the reason that won is that this allowed for recovery in the face of understandings and as long as the chance wasn't that large the cost also wasn't.
