it should work - it's up to society to make this work by passing laws to that effect.
As soon as they introduce their own bias(curating content, recommendations, emergence of so called "walled gardens") it opens the floodgates.
The history of communications and information is rife with channels and sources of all description being controlled.
If anything, "neutral" sources are all the more subject to influence as they simply abrogate the role of censor / amplifier to others. All the more so if they're heavily used and relied upon, as this means that there is an influenceable audience present.
As my friend Woozle puts it:
Because of a high percentage of the population being present, there is now substantial power to be had by influencing the discussions that take place.
