Yeah, I probably wasn't obvious enough--my point was that if your hypothesis is "big companies capture academic fields," then you would not predict a world where economics, and only economics, is captured by "big multinationals." (And why "multinationals" instead of, say, the many large and powerful companies that benefit from tariffs and other protectionist policies?) To me (like you), that suggests that GP is telling a just-so story about why we can ignore economists.
