Yup, which points out the fundamental problem: Facebook is a product of its incentives. Its incentive is to maximize engagement. Why? Because more engagement equates to more ad revenue. The externalities of this behavior do not align with what society seeks. Therefore, if we wish to fundamentally transform Facebook, then we must change the incentives. The incentives are not going to change on their own. Enough time has passed to demonstrate that the market will not correct for this. This can be deemed a market failure. This means some intervention by the state must be made. I propose that having the platform free should be illegal. Instead, the company should be forced to charge customers a recurring fee, sufficient enough to cover operation costs, and to no longer obtain revenue through advertising. This, I believe, will shift the incentives to produce the behavior we as a society seek. Facebook will no longer optimize for engagement, as that no longer drives revenue, and must instead compete on something else, like quality of experience on the platform. Of course, such policy would have to be applied across the board for all social networks as to not undermine Facebook's existence with a competitor offering the same service for free.
