It's not that Burton hasn't done good things for the industry. It is the fact that Burton takes credit for everything. The whole attitude of "I invented" that simply isn't the truth, just a really well marketed spin. Snurfer, Sims and Winterstick were all making boards when Jake came out with his first board. His first board was basically the same product snurfer had already been selling for years.
I am not sure whether you are referring to the specific documentary or are speaking in general. I have not seen the piece, so cannot comment on that specifically. But if it is the latter, I strongly disagree - in my experience (both from what I read in the media and personal interactions) Jake has been nothing but gracious and has always gone out of his way to give credit other people in the industry.
