I suggest reading "Bastard Operator from Hell". Historically ISPs could read all email, see all AOL chats, and all the search queries. They could see you entering your payment information. If we go by fisheries example, there was no privacy in the 90s. It's reasonable expectation that you trust someone with your information. I feel lake author falls into imaginary world fallacy, where people don't know that the meat comes from killed animals, or that cooking is not normally done in latex gloves.
