GL/LFL do listen to the public on certain occassions. The reason he's partly releasing this 'GL Blockbusting' book is to counter the argument that films like SW and Jaws created the modern Blockbuster movie concept. the book didn't come about because of one or two people saying the idea, but by having the idea percolating and repeated by sources on all levels until GL/LFL felt they needed to counter the argument.
So will RedLetterMedia's piece change things no, but as Zombie has done with his book (http://secrethistoryofstarwars.com/), they've added weight to the argument/idea by putting their ideas behind the concept to support it. Over time that argument could be the prevailing wisdom or maybe not.
