In that case, I wouldn't be so sure about your numbers because people will lie about positions if they think they'll be negatively impacted by a "wrong" answer.
This is one of the reasons why the 2016 election polls were so wrong. When polled, a certain number of Trump supporters would lie and say they supported Clinton.
Facebook and to a lesser extent other big social media is in an impossible position.
In my opinion: “Over time, in general we tend to add more policies to restrict things more and more,” he said. “If every time there’s something that’s controversial your instinct is, okay let’s restrict a lot, then you do end up restricting a lot of things that I think will be eventually good for everyone.” is right on target.
I don't mean to understate or under-appreciate the damage and impact various posts can and do have. This one post by Trump will likely cause tangible harm.
There are absolutely no unambiguously good and correct decisions here. Facebook and the others are in completely uncharted waters.
Facebook cares about its bottom line only. By restricting things, it decreases its income. They don't want to verify ads (my dad was just scammed the other day. I have since gotten my mom off of Facebook). They don't want to lose users, that includes nazis, white supremacists, Trump supports, far left radicals, etc. They don't care about hackers, and foreign agents influencing elections.
If Facebook wishes to be a public forum then it needs to either become a utility or it needs to lose its profit incentive. Otherwise it is a private platform and should bear the consequence of the misinformation and hate it spreads.
