A clear example of how speech on Facebook has everything to do with power and money and nothing to do with the principled defending of speech because (as Zuck said) “The ability to speak freely has been central in the fight for democracy worldwide".

Facebook might have actually had its hands tied here, but the point is that content on Facebook is subject to the influence of power and money, not the influence of principles.

At least the notice is "X says Y is false" rather than "Y is false".
