It's not bad advice, but it's becoming increasingly difficult as the front of surveillance capitalism[1] advances to capture more territory. The opt-out options we have are disengagement and legal requirements, both unsatisfying. The latter because territory advancement outpaces legal countermeasures, and because legislatures are in bed with the very corporations who create these systems. It's a broken system because it's prone to this type of exploitation. Before we switch to solutions, I rule out moralizing their behavior, it rarely works, but developing a more nimble conceptual antithesis is required.

1. sorry I don't have a better term. this seems to be the most prevalent name.
