So by your logic, a drug kingpin who doesn't actually handle the drug-selling transaction should not be liable for anything, even though the money rolls up to them?
Ross directly profited from the sale of those drugs. So, yes, he was "selling the drugs".
Google and Meta also profit from selling ads to the people who use it to trade drugs. All I'm saying is there's a rough equivalence. Perhaps the Silk Road platform should be banned but he was not a drug dealer himself. Creating a communications platform is not the same thing as being a drug dealer.
