The premise of the episode, Kyle not reading the Terms and Conditions", doesn't make any sense for him (it could still be valid for the two adults). A minor can disavow ANY contract at their whim (except for "necessity of life" things like food) at any time up to six months after their 18th birthday. All he had to do was tell them he cancels the contract.
Why would Stan not know what the men Kyle said were trying to kidnap him, want? Kyle said it was in the user agreement he agreed to, to which Stan and the others around him then said they always read the user agreements. Stan would already know what creepy things the suspicious men want.
