As you've said in today's world it is difficult to operate a 'free' web-service without ads and ad-tracking, and I always thought since I am using their service I could give my data for ads since their business depends on it. But after thorough research about tracking I agree with you that these decisions must be informed and if this is not acceptable, either I should be denied service or the business model should be changed (after enough users like you and now I chose not to be tracked, I believe it will change)
