This is so wrong, on so many levels. They will capture your clicks, your usage patterns, your interests, and the internet will present to you in a non-neutral way, in a way which will not be in your interest, but in the interest of whoever is paying for the results of your data analysis. A way which will influence your perception of reality in microscopic and permanent ways, because they will know you more intimately than you know yourself.
Do not interact with surveillance capitalists. You will lose.
One should instead protect its behavioural breadcrumbs and try to use non surveillance ways of communication.
