Everyone has the right to speak.
Only the rich have the right to be heard.
Information theory requires a signal-to-noise ratio of 1.0 or higher for signal to be detected. Thus any message signal can be effectively censored by amplifying the noise that surrounds it. Corporate media, i.e. the corporate propaganda system, functions to drown meaningful signals in meaningless for-profit noise.
I call this process “amplified noise censorship”.
