They have to be over the top and as hysterical as possible to get attention, I'm afraid, or they'll never get on the news. Going up against big energy companies is like climbing Mt Everest. They have to figure out how to get answers/information, without appearing to be crackpots.
Oh, a thought. The fracking fluids can't be that much of a secret, I mean there must be a lot of people in that business that know. I wonder if they're reticent to list everything in case the chemicals they buy turn out, under analysis, to be contaminated. They could be worried about getting crucified if something not listed showed up. OK, it was just a thought.
