`  The section on ``Funding`` tries to paint the sources of funding for this film as entirely grass-roots (``In order to maintain full transparency and keep the film free from special interests, McAleer and McElhinney returned all donations from companies or senior executives in the gas industry``).  But this is true-the movie was produced promoted by conservative groups.  Furthermore there is evidence that the ``grassroots`` funding was actually ``astroturf``-most of the small donations were made by employees of companies involved in fracking and at the direction of corporate executives.  There has to be something in the article to explain that the claims of entirely grass roots funding are not without controversy.`
