Yet in real life gifting, we expect reciprocity and have norms. (E.g., if little Johnny doesn't bring a present to Sally's birthday party, he never gets invited back.)

Asymmetrical gifting is only acceptable with a power imbalance; if the boss gives an employee a gift, it need not be reciprocated.

FOSS actually turns this on its head, since unpaid volunteers are giving billionaires like Bezos gifts. Worse, people argue in favor of it.
