Context matters. In this case it was a challenge because of previous research and I would've done it just for fun and the experience. I'm lucky I can afford to do that. Doesn't mean I don't value compensation.
In other cases maybe yes, maybe no - for some nonprofit, maybe someone needs help? are they a business and can they afford to compensate this kind of work? maybe it is some prominent product? there is no simple answer
