That is so off-base as to make me think the guy knows nothing. I used to work in corporate finance for a major natural gas producer. The idea that there is collusion is totally nuts. Not only is it very competitive, but there are even secondary trading markets to ensure such. Plus, there are endless numbers of natural gas producers. It is one thing to allege collusion in refinery production, but quite another in natural gas production.
