As far as I know, AWS is not an ISP-- it's a business, a bit like the one not selling cakes to homosexual individuals.
Remember, AT&T is also incapable of stopping criminals from conspiring using text/telephone messages...and based on your logic the Feds could just shut down AT&T and blame AT&T for being "complicit". No obviously that's moronic. Wake up and stop giving our rights away. Eventually you're going to loose your own.
