To me, there's a compelling case to gain the means of manufacturing prohibitively expebsive, lifesaving drugs.
Are people concerned about safety, or misuse to create harmful chemicals or hard drugs? I'm not sure I understand why anybody would be against the idea of understanding how these medications are made.
If you watch the video he talks about the large number of people who are dying because they can't get the life saving medicine, often because of insanity inflated prices. With one medication they synthesized was purer then what you can get commercially.
I had seen the whole thing through by the time I had posted. I see no downside to what this group are doing, I was mostly curious as to why people were against it (if downvotes could be interpreted as such).
