It's called "Astro Turfing".

I'm not alleging that the Pharma Companies invented the idea of being against vaccines. I'm alleging that they actively fund modern Anti-Vaxxer campaigns, because it puts ALL CRITICISM of pharma companies in a bad light.

A few years ago, if somebody was critical of the Pharmeseutical companies, the average person in society thought they were a good person, who was just trying to help.

Fast forward a few years, and now, with the Anti-Vaxxer mover's antics being played on a loudspeaker, somebody who criticizes the Pharmeseutical Companies is often lampooned, or accused of being crazy.

The people criticizing the Pharmaceutical Companies haven't changed. It's the introduction of a prominent(and very misguided) anti-Vaxxer movement, that has caused the change.

You can totally support universal healthcare and criticize the revolving door between regulators and industry without anyone ever calling you an anti-vaxxer.

May be true. But it's a rare occurrence on Reddit. I've been accused of being anti-Vaxxer, for my anti Big Pharma stance, many times. Wanting greater regulation on all medicines(Including Vaccines) has become a position that's more controversial to hold in America, than nearly any other.
