content: That's a perfectly valid question.  Nothing should prevent them from being left-leaning, or right-leaning or anything they want to be.  The question is, should someone like Twitter be held accountable for what's on their site? Let's say, just to remove politics from the discussion, that Neighbor A tweets horrible lies and slander against Neighbor B and harms their reputation.  Should Neighbor A be held accountable and/or should Twitter be accountable? That's addressed in the Communications Decency Act, specifically Section 230, known as the Safe Harbor provision.  The issue is that, to carry the example, companies like Twitter want the enormous protections of the the Safe Harbor, while simultaneously ignoring the requirements of the Safe Harbor. Section 230 basically says, and I'm hugely paraphrasing here, that a company is a Information Service and NOT responsible for their users communication, as long as the company does not exert control, approve/deny, or review their users communications prior to them taking place.  If the company does those activities, then they are not an Information Service, rather a Publisher.  This makes the speech of the user effectively the same as the speech of the company...  If the company is making the speech, then they are responsible for it. So they want it both ways: * Lies about Neighbor B?  Not our fault because we don't review the information. * Someone post child porn?  We'll remove it because it's against the rule, but not our fault because we don't review the information. * Anti-Semitic? Not our fault because we don't review the information. * Anti-Christian? Not our fault because we don't review the information. But at the same time: * Pro-Democrat?  We'll give you special "Blue Check" status. * Pro-Republican?  Limited distribution. * Trump?  Fact-checked, editorialized, deleted. The very act of editorializing, and approving and removing makes them a Publisher...  In order to get the protections of the Safe Harbor, you need to follow the requirements of the Safe Harbor.
