Sir, first I should say thank you for your interest in Facebook and for your use of our community. We appreciate it when people are engaged with our service and use it to communicate.
As you note, we have recently seen a number of people posting comments on their Facebook timelines that say essentially, “I don't want Facebook to own my content”. The concern is that if you don't post this statement on your timeline, then Facebook will own your content.
That's not true. We say in our data use policy that the users who post content own it. They give us a limited right to use it in connection with Facebook, while it's on Facebook, but they own the content and they have privacy settings that control how it's used.
We've tried to engage, over past day or so when this has come up, in communications with our users in a number of different ways, to help them understand that this is the case and isn't something they have to worry about.
For example, we have a Facebook and privacy page where we've posted some information about this and a link to our policy so that people can read the statement for themselves. We have a fact-check section that we've launched on our website, so where there are rumours that people want to know more about they can go to that place and find it. Obviously, we've talked to the media as well. We hope that people will feel comfortable sharing on Facebook.
