Because companies make decisions based on who has the most money. 90% of Americans have basically no control of those decisions. And companies interfere with democratic control of the government. Getting things out of the way of democracy seems good to me.
Again, how would that be different if government had the power to control information? Its human nature to do things that benefit yourself. At least if its not centralized then you have competition which gives people a choice of where they want their information coming from.
We already know that organizations (whether public or private) eventually devolve into a bureaucracy where the goal is the growth of the organization itself.
We see this with the government - how often does the government ever remove laws? Or reduce size? Very rarely.
It seems to me that if the goal is to ensure one is not coerced, whether by business or government is not to try and create mechanisms to ensure coercion is only benevolent, but rather to ensure they never have the power to coerce people in the first place.
