Child labor is similar in some ways, but I do want to point out some important differences. Children are not legally able to make contracts. We recognize children as being unable to rationally process on the same level as adults. To the extent adults have a problem with hyperbolic discounting, children often have that same problem but much worse. And children often have no choice but to obey a person in authority over them (typically parents). If you put all that together you get a perfect storm of terribly misaligned incentives and vulnerability that make child labor a very different case than what we're discussing here. It's entirely possible or even likely for a rational service provider to throw in a freebie in exchange for intangibles like publicity. It happens all the time in the adult world. So I don't think child labor is a fair thing to compare this situation to.
