Exxon Hates Your Children - "banned" - PSA Houston

So "Exxon hates your children" is a 'nationally crowdfunded PSA, where you the viewer can toss in a dollar or ten, a click or twenty to help fund getting this ad on the air. It's aired in Denver, New York and Washington DC but when bought air time in Houston on Fox Exxon decided to issue a cease and desist demand and threaten Comcast into not airing your PSA as scheduled.
Interesting. Now, since i haven't read the C&D I don't know if it's about trademarks which would be something one has to C&D about. My god I hate lawyers so much. Sorry, did I say that out loud?
