And it gets worse the smaller the market is: There is a chance that a youtuber with sufficiently large following could actually choose to buy said mac pro, because their revenue might be pretty large. But then you look at, say, boardgame reviews. Nobody, ever, buys a game. But the number of views isn't good enough to dedicate the time to it as anything other than a hobby. Thus, anyone posting enough that they make it their job is also getting sponsored on top of the free product, but nobody wants to tell you that. Thus, all you are seeing is 100% ad, just shaped as a review, or as entertainment.
