It is natural that owners of the platforms for public expression impose their rules on what is allowed to be expressed. It is the monopolization of such platforms, their uncontrollable growth and ruthless elimination of any competition, that makes them dangerous. Look at twitter, facebook, google - they are all monopolies. As are cnn, bbc, and such. Which converts them in valuable tools of mind control, destroying humanity's most fundamental need - to freely exchange information and share opinions.
