Will that really protect you? Won’t your ISP still have a full log of all your HTTP requests? I believe that’s what they’re talking about selling, if I understood the news stories I watched. Which is different from what Google and Facebook mined and sold in the past, so I don’t think the “it’s been going on already” argument is true.
The ISP will have a bunch of gibberish. They would have to have all the data of your ‘exit node’, which changes every time you connect (ideally) and which is not even in your own nation. While they could still sell it there would be nothing of value or interest to a corporation.
