No, but subjective assessments, summaries and, comments are often influenced towards whoever pays the bills. Not that dissimilar to what happens with politicians and lobbyists in Congress.

Why do you think we pay the highest price in the world for common prescription drugs that can be purchased in Canada as one example for a fraction of the USA's cost? Why do you think there is a prohibition in the federal programs against negotiating prescription rates similar to what major medical insurers do? How many major military defense contracts moved forward after massive cost overruns even though the system in question may not even be what the D.O.D. wants or needs? Follow the money. Why do you think there is a movement to force Social Media personalities to disclose their financial ties with the products they promote?
