The right to say something is not to be confused with the right to be paid to say something.

In fact, monetization creates a perverse incentive to prioritize financial gain over informing the public.

So, the central point (or one of them, at least) of Manufacturing Consent is that news/media organisations are shaped by what advertisers desire, such that the reporting is mostly friendly to a capitalistic worldview.

This is 100% analogous to what Google are doing with respect to demonetising youtube videos, and troubling for exactly the same reasons.

Isn't it troubling that the videos are not created to inform, but to keep the audience paying for them?

Yeah of course. But I'm not sure what else one would expect, given our societal structure.

If we can remove one perverse incentive at a time, it's still progress, but i agree that, without punishment for misinforming the public, and it's delicate to draw lines there, the problem won't go away.
