I see this was downvoted, not clear why. Let me point out that a video store telling someone what videos you rented was outlawed https://en.wikipedia.org/wiki/Video_Privacy_Protection_Act https://en.wikipedia.org/wiki/Video_Privacy_Protection_Act In other words, I'm not the only person who thinks others shouldn't be able to know your video watching history. I'd personally like to see it outlawed that sharing a profile of your video watching history also be outlawed. In other words, while the law above is about the actual movies I don't want Netflix (or any other company) to be able to share even the type of movie. It's one thing for Netflix to use that data to recommend movies. It's another for Netflix to be able to sell a profile of me (likes action movies) or likes (likes sexploitation movies) or (likes movies with LGBT themes). That last one I think really makes the point clear. Netflix should not be able to out you to other companies and that means it should be illegal for them to share your profile even if it doesn't include your actual watching history. I'd argue the same should be true for Google. They should probably be allowed to profile you and then let advertises say "I would like to target my ads to people who fit profiles X, Y, and Z" but Google should not be allowed to share that profile outside of Google.
