Unilateral changes with little or no notice
You are agreeing to be bound by updated Terms through continued use.
“Unless otherwise required by law, we will notify you before we make changes to these Terms... Once any updated Terms are in effect, you will be bound by them if you continue to access or use our Products.”
What that means: You lose control over contract updates; using the service after changes means you accepted them.
Meta can update the Terms at any time and binds users to new versions simply by continued use, rather than requiring explicit renewed consent.
