I don't know that I would presume to even understand the aspects of Facebook enough to fix it.
What I know we can focus on is primarily two ways. I always put technological solutions first. What we want to do is put the user in control of the data and of access to the data on their device. We've taken it upon ourselves as part of our platform to put the operating system as a barrier between applications and the user's data, and to require that user's consent, as mediated by the operating system, to come in between that app and its data. This is a set of things that we've evolved over time.
You've heard comments today about trying to keep usability front of mind as well, so we're trying to keep things clear and simple for users to use. In doing that, we've built refinements into our technology platform that allow us to expand that set of data that the operating system.... Again, this is separate from Apple, the corporate entity. The operating system can take a step forward and put the user in control of that access.
That's a process that we're going to remain committed to.
