Does most of the money made by professional "YouTubers" come from Google or is that just a secondary income stream that is completely overshadowed by product placement and the like? This surely varies from show to show, but those where Google is just a minor part could potentially gain a lot more from the increased exposure than what they would lose in formal ads. One might question wether those shows qualify as "quality content", but it's Facebook, expectations are already low (not that they would be terribly high on YouTube). I expect a lot of crossposting.
