1) The article writer completely missed Feynman's point. Feynman is talking about the nature of reality, not about society and its actions. If I say "bricks are nutritious" and the government forces everyone to eat nothing but powdered bricks, that doesn't change the fact that bricks are not nutritious.

2) There is a slight caveat to Feynman's point -- if a theory disagrees with experiment, it's possible that the theory is correct but the experiment / data interpretation / etc was flawed.
