About online ads, is most of the tracking and code that runs to identify my preferences or is some kind of anti=fraud shit,that will get even more complex and invasive as bad guys will try commit fraud. I am thinking at a partial solution(emphasize on partial), offer the users a non-tracking account(Free) , you still give them targeted ads but using a non tracking method like a survey at account creation, options for the user to tell you that he does not like this type of ad, options for the user to tell you what kind of ads he wants to see (like I could accept non-animated ads, software related, local business related, technology related, and article related ads). But all of this would be impossible if most of the tracking is for anti-fraud , then you would need some DRMed browsers to confirm you probably are a human.
