Yep — human reproduction is not an equal deal for the participants. In the most basic sense possible, it is not fair. Nobody promised humanity that our alien-god-given bodies would perfectly implement the rules of morality that we might later derive — such as reciprocity; or for that matter not using another person merely as a means to your ends.

This bug has been acknowledged many times before, and various technical and social workarounds have been proposed and deployed. The underlying bug still needs work, though it may not be fully fixed before humans are ported to a new platform.
