The people there are completly villifying GL and calling him little more than the conduit through which the idea of Star Wars flowed and was taken up by better qualified people. They basically believe that ANH turned out the way it did because of the intervention of others, and that TESB and ROTJ turned out the way they did because GL took a back seat on them. ONe individual even called him a "meddler" in his own films.
Basically the whole paragraph is referring to my refutation of Lucas as sole author/auteur. But the specific reference to "ONe individual even called him a "meddler" in his own films" oh yeah that's ALL ME BABY.
