It would be nice if I could actually believe that they're doing this out of any human sense of kindness. Of course since they're all publicly traded companies, they have absolutely no reason at all to even think about such petty things as "human kindness," beyond what PR demands, and instead focus on the profit margin per share for the next quarter. This is a pittance to keep the public from demanding government oversight that might actually, you know, result in affordable prices, or any actual regulation of drug companies.
