And most people don't have issue with static ads like those in newspapers and magazines. People would be fine if business wants to advertise something, but the tech ads industry does not only want to promote things to you, they want to capture your attention as well, regardless of if you want the thing or not. They think they can only do so by knowing you as well as your mother does.

If a business have something to sell, just let people know. No need to help create a surveillance state.
