I think this also explains why google search results have gotten noticeably less useful. There's not as much money in providing an answer/instructional content. There's a lot of money in pushing products. The danger is that if google search/youtube goes too far in the direction of pushing products, users migrate to a different platform that will better serve the less profitable need (relevant search results).
