Maybe you can do the analysis you mention and publish it? The worst that will happen is that all us laypeople will be better informed.
I think though that CostPlus, if nothing else, has opened the eyes of a great many people who just assumed medicine was like any other product where the manufacturer controls the price and if someone is making obscene profit, it's an outlier like the Shkreli douchebag. Now a lot more people know that it's possible to pay a lot less. Even on TikTok I'm seeing people paying much less for their prescriptions when they bypass the insurance company and pay full retail price, which is counterintuitive as hell, and I personally would have never guessed.
So all in all, I think it's hugely positive that the secrets are getting out, and CostPlus is invariably a large part of that.
