How so? I do see where it talks about only doing preventative measures when working for insurance, but it also implies that not all their work is for insurance companies. One of the links to the LA times even talks about a homeowner hiring a private fire fighter to save their home, and these instances involve actually fighting fires, not just clearing brush.
