If we can't get privacy using crypto, we could always use chaffing to make their database useless. We just need a list of sensitive websites that want to hide their true users, and an ad-serving network that randomly serves up links to those sensitive websites on other web pages (but doesn't display them). In this way, everyone's browsing history will look suspicious, so the data won't be of any use.
