[Update: I did not read the original proposal carefully. I mistakenly believed this was a mandated regulation and not a voluntary one, so some of the points in my post do not apply. However, I still oppose it for mostly the same reason: if consumers wanted this type of label on their products, then we we would likely already see it. I am also skeptical that this is being initially proposed as a voluntary program, but…
Or, maybe, companies are exploiting consumer ignorance and we're not dealing with an efficient market.
