... Zuckerberg's instincts are 100% correct. I don't understand why people (usually democrats and the left now, but it could be right-wing evangelicals in the future) are pushing for social media companies to wade into the quagmire of politics. Twitter's 'fact check' of Trump's tweet is a perfect example of what happens if you try. Their fact check was wrong because it missed nuance and context of issues with mail-in ballots (as in, there is potential for fraud with related actions like 'vote harvesting'), and it pissed off people (not just Trump supporters) because it was ad hoc and arbitrary because you can easily find Democratic politicians making erroneous statements. Almost everything a politician will say is wrong in some way and from a certain perspective and having minimum wage Twitter reviewers be the arbiters of how political speech should be interpreted and in which way is a recipe for disaster.
The "Citizen's United" ruling came around when the FCC tried to enforce rules against political speech arbitrarily when they decided a right-wing documentary critical of Hillary was deemed to break election laws, but Micheal Moore's Fahrenheit 9/11 (which was also purposely designed to influence election) was not. And you know what, that is unfair. There is no universe in which it is fair that Moore's documentary gets to be exempted but a right-wing group's documentary doesn't. And because of the arbitrary politically-motived actions of the FCC, we ended up with completely unchecked election spending.
Get tech companies out of politics. If not, it will blow up in your face.
