Facebook has updated its terms of service and data use policy recently and the changes have upset many people. I’ve started seeing more declarations of users’ intention to opt-out of provisions of Facebook’s terms and conditions. These sorts of declarations seem to be legally binding with their fairly legalistic language but they don’t work except to help you feel better.
The only way to limit what Facebook can do with your content and your personal information is to stop using Facebook and to delete your profile. Unilateral declarations of your intention to opt-out of provisions you don’t agree with don’t make those provisions less binding on you.
If you use Facebook, you do so on Facebook’s terms. If you don’t want to be bound by those terms and conditions, stop using Facebook.
