There seems to me a huge difference between a few organizations being able to produce & distribute a total of X amount of self-serving bullshit with some limited reach, and anyone with a bit of money being able to produce 100,000 • X amount of self-serving bullshit and deliver it to exactly the people most likely to respond to it the way they want, anywhere in the world (save, notably, China and North Korea and such) while making it very hard to tell who it's coming from.
An environment in which 90% of the information is adversarial is really bad. It's a severe problem and very challenging to navigate. An environment where 99.9999% of it's adversarial and it's even harder than before to sort truth from fiction, functionally no longer has any flow of real information whatsoever.
