The more data companies have about you the more they can arbitrarily charge you more.

For example, they realize that those people who listen to heavy metal and talk to themselves are more likely to get into a car wreck.(Please understand this is a made up example). So because Someone can use your car and your phone to listen to you, And they can also figure out your music habits. Now they realize they can just charge you more for insurance.

Because evidence could be made to say pretty much anything you want .actually that falls under unreasonable search and seizure and privacy, but you still get the idea. Privacy is very important
