>If the majority of these users are looking for privacy they probably wouldn't trust facebook with their data in the first place. This assumes they know and care that they're being tracked. Once faced with a clear choice without any dark patterns, it's fairly obvious that most users will select no tracking, unless the (supposed or real) benefits of being tracked are also explained to them. With the default Facebook behavior, they simply aren't being reminded of it. Out of sight, out of mind. It's been known forever that opt-in data collection is almost useless, because the overwhelming majority of users won't allow it if they have the choice, regardless of the expertise. In fact, it's the reason for the current state of things - the telemetry and tracking of all sorts are being forced by default in most of the software and services with no option to disable it.
