In their to this response, the authors of the study clarify their reasoning for attacking the cigarette companies, even though they merely complied with the law:

Moreover, the FDA's actions are sending the wrong message to the public. First, the FDA is indicating to the public that there is such a thing as a safer cigarette. The FDA is insinuating that even small changes in cigarette design can result in drastic differences in the public health safety of cigarettes.

For these reasons, I believe that electronic cigarettes are a much more viable option as a harm reduction approach for smoking cessation.
