I dislike this framing. I was paid money for over a decade to write GPL'd code; I didn't do it as a gift. I release my code under the GPL for selfish reasons: I want others to be able to improve it, and me to be able to take advantage of their improvements. To me, it's not a gift, it's just the most efficient way to write software.

I suppose that metphor depends on what you think of community efforts. Like say, sharing a food recipe or a workout routine. I see see the framing as "giving it away". Even if your endgoal is an ultimately selfish search of "better recipe/routine to use".
