The first is that we encrypt all the data that we can, right? So if we wanted to turn around and sell that data to somebody, we can't. It's mathematically impossible for us to do it, right?
Bart Butler
So we've tied the value of the business and the growth to the business to protecting our users, so that our interests are aligned.
