Your comment seems to be missing the forest for the trees.

Privacy advocates aren't looking to let companies invade everyone's privacy as long as they do it right, the advocates want to stop it in the first place.

Have you considered that a company could use unintrusive technology, operate on private data only to the extent fundamental to delivering the product the customer has purchased and removing the surveillance clauses from their contracts of adhesion? I suspect privacy advocates might possibly leave them alone if they did that.
