I think the issue here is one of informed consent. You might say, "OK, this makes sense" when agreeing to location data for a weather app. In the context of whether it's going to hail soon, location is reasonable. What you only see in those GDPR-type banners is that the data is being re-sold off to 1001 "partners", none of whom are important for my hail-to-head concerns. Never mind all the cases where it's re-sold on to all the governments and personal-level creeps through aggregators.
