Many years ago, marketing companies would pay people to take part in surveys. It was not much money, but it was something.
Today, they are paying the people who steal the information from us. It is no different then if someone comes to your home and loads up all the items in your home so they can sell them, while not giving you a penny. I think there are laws to deal with that circumstance, yet in the digital realm, theft is quite acceptable.
At least when the guys are emptying your house, you know what is being taken, which gives you a sense of value lost.
Today companies make billions off the information everyone freely gives away. I would not mind it if they gave the option to opt out or paid me for my information, but to just take it strikes me all wrong. I know I am in the minority on that.
