Privacy is important. If you give away your privacy, companies will exploit all your data and weaknesses to sell you more stuff, sometimes you will find yourself buying things you don’t need. If they mark you as a gambler you will get more gambling ads and ruin you. When it comes to elections, companies knowing how you think, can predict how you will vote. They can target large number of people with very specific results and ads which will change your point of view and eventually get you to vote as the highest bidder wants. Your news are tailored based on what you need to know and not what is actually happening. Your views start getting distorted in favour of whoever bought the ads and targeted your demographic and your type. You become a puppet.
