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."

Why Why Why Why Why
Why should my personal information remain private?Because my personal information gives me access to my money, my personal contacts, my identification, and I don’t want that to be taken advantage of.
