I value my privacy. I don't have a relationship with data brokers and I see no need for them to know anything about me. For the record, I have no issue with targeted advertising within a single org. If Google shows me ads based on my search history or youtube history or gmail contents, that's great. If I don't want Google to know anything about me, the process is easy; I stop using Google/Youtube/Gmail. If Google shows me ads based on an online purchase at an unrelated web store, that's completely unacceptable. If I don't want Google to know anything about me, it's not clear at all how I would do that.
