Are you conflating theories here? Any research recommending alternative strategies for iterated games is almost certainly looking at repeating games between a consistent pair of players. I’m not in the field but I’ve never heard a theory that a generous strategy works in a game between an arbitrary number of (mostly) anonymous players. And to call this event part of an iterated game at all seems… unusual.
