Isn't the point that "choice" as you're defining it is a conscious, system-2 process, but the algo-served content is targeting much deeper, system-1 responses? If so can we say that people "prefer" to watch it, or that they've been conditioned to consume it? The question (to which I don't know the answer) is where does free will start?
