ISPs vs. Google/Amazon/Facebook

http://tcrn.ch/2nhnAI1 "Not only are users unable to control what traffic the ISP sees, but frequently they have no alternative; no Protonmail, no DuckDuckGo, no Signal. Much of the population gets to choose between two or three providers if they have any choice at all. This lack of choice puts ISPs in a different category from edge providers."
