If you really want to avoid internet privacy concerns, stay off of the internet. If you are so paranoid that you trust no one on the internet, stay off of the internet. If you want to be part of the internet, you have to make a reasonable guess as to what to trust, and ignore the paranoia where you find bad things everywhere. Even being off the internet, someone somewhere is still tracking you in ways you don't even realize. Living as a hermit in a cave on an island with no people is not a lifestyle most people want. DDG is still way better than any other option.
