You and I are completely insignificant in the face of this horde of people who are becoming increasingly vulnerable to subtle manipulation. That's the point of this article. A rising tide lifts all boats.
We're past the point where telling people to stop using the services would have any measurable effect.
People were made aware that smoking causes cancer, vaccines do not cause autism, and that man-made production of CO2 was causing accelerated climate change. In each of those cases, there are experts in the field warning common people of the danger. In each of those cases, the experts observed that people didn't know about the dangers beforehand. In each of those cases, there are people who refute the claims of the experts or flat out do not care (I should note that plenty of intelligent people fall into this last category).
I expect this scenario will be no different.
