Corpos like to lie, and their promises to not sell data is worthless. Even if they're not outright selling data directly, or "anonymizing it" before selling it, at a bare minimum they're still abusing the hoard of data they have to make a buck. They want that data and get large amounts of it through people's broswers, even with adblockers installed.
