It's certainly controversial, and rightly so, but I think it's a fair, 30 second shot, at a company that is killing a lot of people through their unhealthy food, contributions to polluting the environment (be it trash or support of Factory Farming), and is even fighting to keep toys with "Happy Meals," knowing full well that if you hook'm young, you'll get them for life (albeit, a shortened one).
Here's a link to the PCRM page where it's also posted with some information. And apparently, many people in South Florida won't be able to see it. Nice work, PCRM. Over a million views on YouTube already.
