I'm a little more hopeful that regard, perhaps misguided. Shkreli is a commonly known name because of his persona and the way the media latched on to it. It was a perfect story. Bad guy, doing bad things to sick people. Hell I even know how to spell his name and he has been in the news for quite a while.
Questcor on the other hand, I've never heard of. Not a very juicy story, and any juiciness is the result of Shkreli. Will it make a difference? There is a lot of money preventing it from making a difference, but it's about to become a political career killer to allow this to go on I believe. At the very least, it's in the public discourse.
Comparatively, Snowden's revelations hasn't really changed squat either. Maybe I shouldn't be so optimistic.
