Also just by observing what they’re doing it becomes pretty clear. For example: Facebook recently purchased full-page ads on major newspapers entirely dedicated to “denounce” Apple. Why? Because Apple has built a system-level feature on iPhones that allows users to very easily disable every kind of advertising tracking and profiling. Facebook absolutely relies on being able to track you and profile your interests, so they immediately cooked up some cynical reasons why Apple shouldn’t be allowed to do this.But the truth is: if Facebook is fighting against someone on privacy matters, that someone is probably doing the right thing.

“We believe that this is a simple matter of standing up for our users,” said an Apple spokesperson in response to Facebook’s first full-page newspaper ad yesterday. “Users should know when their data is being collected and shared across other apps and websites — and they should have the choice to allow that or not.”
