The problem is that FB wants to eschew all of the responsibility for content running through their platform and run everything 100% programmatically for scale. They expect the advertising user to know what's kosher vs what's not, and they expect the advertised-to user to moderate content. They refuse to put in place even the most basic of business controls. That strategy uh... doesn't work. As evidenced by their many FTC consent orders and massive fines.
In short, why would they even want to be seen as possibly having that power?
I'm not sure I see anything that supports your conclusion. Have you considered what evidence would make you change your mind?
If McDonalds advertizes how good and healthy their Big Mac is, is it political? What if someone complains that it contradicts some pending legislation? What if someone complains about the racial make up of the cast in the ad? What if the ad mentions a word that later someone complains about?
We live in a nation where we can't agree on what a man or woman is, and what that means. In fact, just talking about it is now political.
So, who's going to judge whether something is political or not?
