The problem is the freeloaders of the internet far outweigh the people that want to pay for services. Until that changes, we will continue to see the internet dominated by targeted advertising. Honestly, it will be interesting to see what happens to services like DDG. I think it will be a true test of what the world wants, an extremely well funded machine like Google or a more lean privacy centric tool. Capitalism is an interesting thing though. Targeted advertising naturally brings in more money (back to the freeloaders point)
