Meaningless comparison. Assume for the sake of your argument that the G&M is completely biased and completely repressive: we all have complete freedom to turn away. The G&M's ability to sway public opinion is considerable, but quite limited. It is a business and if we withdraw support the G&M will fade away as quickly as Sears. 
There is one president with enormous power, guaranteed coverage by nearly every media organization on the planet. He can literally rain down "fire and fury" in military, judicial, economic and police matters. So yes, if Donald Trump and the G&M were to say exactly the same thing, Trump's power and influence puts his statements on  levels a thousand times more potent than the G&M.
