We're not talking about Apple, though. You're presenting the context of Onavo's actions as though people weighed the pros and cons and made an informed decision about whether to use the app. I'm adding another bit of context that suggests people did not realize what Onavo was doing behind the scenes, and that Onavo concealed their behavior because otherwise people wouldn't use it.
