Obviously a megacorp can get access to anything they want, this is America. Thanks to dupes like you, the sky's the limit.

How do you tell if there's harm from a medication that all people get other than through placebo? Still can't answer the question.

In this case there are questions that are unanswerable because you are too dumb to understand what the question is or how it's relevant.

But here's a hint for you: It's also unethical to put an entire population at risk of harm. This is a trolley problem not black and white morality.

Keep blustering, you're obviously just a schmuck on the internet. If you have to conduct a single-blind study on the entire population of the world to figure out if your treatment is harmful over the long run, better just not to release it. Because, you know, that kind of puts the vast majority of the world at risk of harm?

That's kind of the "ethical norm." You know, the reason we have these things called "medical trials." You should look up that word "ethics" some time, but get someone to hit you in the head with the dictionary first.
