It's true that the media panic was way out of proportion to any possible risks. Still, there's nothing wrong with limiting exposure if you feel that's important. It will take some time for definitive studies on low-level exposure to come out. Meanwhile, I'll bet the coating manufacturers are looking for ways to reduce/remove this chemical from their products. They've been mostly under the radar so far, but the public perception is pretty well set in concrete. That puts their business at risk, and they know it.
