Its claim that it doesn't sell user is based on a narrow interpretation of the word sell," said Arvind Narayanan, a professor of computer science at Princeton University who specializes in privacy. But that leaves users confused and unsettled about what happens to data that feels very personal.

"This business model constantly pushes the company towards hypersurveillance," Narayanan said."
