I keep reading these articles. They say that tax sites "shared" or "gave" user data via active pixels, but is that really true? Don't these companies receive money to host the pixels? Didn't these companies actually sell user data? "Giving" and "sharing" are not the same as "selling", yet not one article I've read indicated whether the tax prep compaies received payment for the user data. Does anyone know?
