This is my take on what Tim Cook should have answered
> If customers really value real, safe drugs, even if there's multiple drug suppliers (some offering fake, unsafe drugs), people should still go to a pharmacy?
That shouldn't be Apple problem, we have governments for that.
> Will people not be able to distinguish between safe drugs and fake unsafe drugs
That shouldn't be our concern, we as the supplier of the market place should only worry about abiding to the law and report those that don't when they use our system
If they don't use our system, it shouldn't be our responsibility.
But Tim Cook is not on trial for selling illegal drugs, he's trying to make Apple look like the only possible guardian of user's safety.
Because it's in Apple interests, not because it's best for users (I mean that Tim Cook can't possibly know if Epic store would be less safe than theirs, he - admittedly - never made that experiment)
