I've read a lot of the "pro privacy/anti tracking" arguments over the years, and (outside of a few exceptions) they almost always hinge upon some aesthetic dislike for companies having this information, rather than having any material justification for why it's harmful.
But attacking ads and ad tracking, the revenue model of the free web, is materially harmful. Imagine how much worse the world would be if Google search weren't free -- even a nominal fee of a few dollars a month would preclude most of the third world from accessing the best index of humanity's collective knowledge (not to mention how much worse the user experience would be to quickly Google something). Humanity collectively would be very non trivially worse off.
Seriously, what other business model besides tracked ads can generate enough revenue to keep the lights on, let alone power growth, at companies providing free services like Google Search, Maps, etc, that don't have such grossly negative externalities like severely curtailing human development and don't offend the aesthetic sensibilities of people who are prima facie annoyed by a company using the interactions with their free service to make money?
