I don't think it's even obvious/common knowledge in public discourse, to be honest. (Case in point: this Guardian article doesn't mention it at all, only mentioning the cost of materials and manufacturing.)

To some extent it may not even matter, since the effects of (negative) public opinion are tangible regardless of whether those opinions are fully informed of all the facts. (And even as someone who's aware of a slightly above-average number of facts, my own opinion skews pretty negative.) God knows these companies aren't in the red, trials or no trials; most consumers are just gonna look at the record profits, then back at their pharmacy bill, and go "Hey, wait a minute..."
