Thanks for the open question. What I'm saying has at least these two elements (not counting tons of negative side-effects or the psychological harm that manipulative advertising causes): 1. Given capital being so unequally distributed, paid ads amount to amplification of the messages from those who happen to have money. In another framing: you see ads about mediocre products with a big marketing budget; you don't see ads about wonderful products that have little marketing budget. 2. The conflict of interest is where Facebook has an incentive not to highlight too much the non-paid posts from people that mention products that don't pay for advertising. If you were to consistently see non-paid posts that gave you all the info you need to get products and services you appreciate, then the advertisers wouldn't be seeing their ads pay off and might cut back on paying Facebook for ads. Overall, attention is somewhat zero-sum. Your attention to one thing is not attention to something else. You never really know what you're missing. But in an ad-driven system, attention is biased toward (but not exclusively) whatever serves those things connected with ad money.
