The main reason the ruling elite abhor freedom of speech is because if they allowed it, they would lose their power.
If 100% freedom of speech was allowed in media, social media...(very bizarre that this should even be debatable) it would, for example, be obvious to everyone that the current global migrant crisis is a deliberate plot i.e cause/effect - Powerful Western elite foment chaos in poor/middle-income countries that they want to control their resources; fund and support a local puppet militarily; country becomes even more politically unstable/chaotic; anyone who can flee the poor country flees, to the rich countries; destabilising the rich countries, too...A massive, inhumane racket.
