Priorities?

I was just reading a well-researched blog entry about the presence of BPA in almost all formula containers currently on the market. The blog, Z Recommends, has long championed the cause of removing BPA from bottles and sippy cups. My question is, has anyone compared the potential harm the BPA in formula cans can do with the harm that the actual formula can do? I'm guessing that the bloggers don't want to start a controversy, and they are trying to serve the interests of formula-feeders, so they will never run that analysis. It just seems a bit strange to focus so much on the harm that formula cans and the bottles used to deliver the formula to the baby can do but to never mention that there is an alternative which is healthier in all respects.

It's sort of like warning people that eating fast-food burgers out of a certain kind of package can cause heart disease but never bringing up the fact that fast-food burgers themselves can cause heart disease. Don't get me wrong, I think the bloggers are doing a great job informing people about which companies are BPA-free and working tirelessly to bring the issue to the forefront. I just wish that they would occasionally mention that not everyone formula or bottle feeds. If you only read their blog, you'd come away with the idea that it's not in the realm of possibility for anyone to feed their infants anything else.
