Better don't believe that Meta will always respect objections to their use of personal data for the training of their LLMs. Imho, even now, they're providing the opt-out mainly to check the temperature.
If the backlash isn't strong enough now, expect them to change their terms of service sooner or later, claiming all personal data on their platforms for their LLMs. They won't back down. And they certainly won't respect anyone's privacy!
