There is no new rule that authorizes Facebook/Meta to use people's photos regardless of when it was uploaded.
Some social media posts and WhatsApp forwards claim that Meta (formerly Facebook) is modified its privacy rules, allowing it to use photographs and other personal information of its users. Further, the post stated that people could post a legal notice telling Meta it isn't allowed to use their content under UCC Law Sections 1-207, 1-308. This bit of information started spreading after Facebook's name was changed to Meta as part of a rebranding effort to emphasize the company's new focus on the metaverse.
However, this claim is false, as the company's data policy and terms of service remain in force, and its name change has no impact on how it uses or shares data. There is no such legal requirement for a Meta user.
According to Facebook's Data Policy, they gather content, communications, and other information the user provides when they use Facebook's products, i.e., when one signs up for an account, produce or share material, and message or connect with others. It can include information contained within or related to the content one provides.
