> I for one am grateful that these services target me with relevant adds. Is that something we want undo? What is the strategy here? Is the objective to be less informed and be directed to information that is non-relevant to our interests? What does "relevant ads" mean? They're more than just ads for something you would want to buy, the message is specifically tailored to you, and they use what they know about you to decide what to tell you and what not to tell you. This is bad enough when it's used to advertise products, it's much worse when used to influence how you vote, given candidates and political parties will have views / policy ideas on many different subjects. Targeting means you only hear about the ones you would agree with, not the ones you wouldn't.
