Maybe cost is a better word. Although there are risks to allowing companies to use your data, especially since right now they are selling the data to companies that are trying to make money off of you, like say car insurance.
I will say thats more an argument for blocking out all types of tracking possible, rather than saying a single one is bad on its own. One place selling your data isnt actually that bad, its when those single nodes are so numerous that you can actually map out what someone does if you chain them together.
Its up to you if you are okay with that in your life though.
