The bulk of the article is about a guy who mixed fentanyl with xanax and passed it off as percocet, but yet the bad actor is supposed to be Amazon?

And it's rooted in this same regressive idea of controlling what people can buy to solve society's problems.
I personally enjoy being able to obtain "weird shit" of all varieties. I don't know what's involved in a pill press per se, but I can't imagine it's particularly complex or tough to improvise. Distributed 3d printing/milling culture can't come quick enough, and get us some refuge from this clueless fear of tools.
