It's especially tough for me because they clearly pushed their sketchy marketing and sales tactics because they honestly believed they were helping people, and in their lifetimes the medical industry lauded them as heroes for "safe" and affordable ways to ease suffering. Right now people have no problem suppressing research they don't like about the negative effects of marijuana or anti-depressants or whatever their de jour personal treatment is - in 20 years if something bad really comes to light everyone is going to pretend that they knew all along and that everything was a smoking gun. Hindsight is 20/20 and history is written by the victors.
