I'm not sure if this was a purposeful allusion or not, but I entirely agree that you "can't recall a gift" in exactly the same sense that you can't keep talking on a payphone for a long time when someone is clearly waiting; because, you know, we're living in a society!!

Unlike the payphone analogy, where there is metering rules, and as long as you abide by them, you can keep talking, even if it's impolite, there is a legal definition for gifts (it is, after all, a transfer of ownership, and such things are regulated), which, as far as I know, matches the social norm of not being able to claw those back.

Ha, except, to go full circle, then if you're using that legal definition of a "gift" requiring a transfer of ownership, it's clear that open source software is not actually a gift, because there is no transfer of ownership.

You can't have it both ways! If it's a "gift" in the colloquial sense of something freely given, then it breaks social convention to claw it back, but it is not illegal. If you want to use the legal definition of a "gift" - ie. for tax purposes, implying a transfer of ownership - then contributions to open source software are not at all a "gift" in that sense.
