Broad license to user content
You are agreeing to let Meta own a broad license to copy, modify, and share your content anywhere, even after you delete it from your main view.
“you grant us a non-exclusive, transferable, sub-licensable, royalty-free, and worldwide license to host, use, distribute, modify, run, copy, publicly perform or display, translate, and create derivative works of your content (consistent with your privacy and application settings). This means, for example, that if you share a photo on Facebook, you give us permission to store, copy, and share it with others...”
What that means: Meta can reuse, modify, or share your photos and posts widely, potentially with third parties or partners, without needing further permission from you.
The document grants Meta a very broad license to user-generated content that is transferable and sublicensable, exceeding what is strictly necessary just to display the content to friends.
