Thank you.
Mr. Vickery, you touched on this in a number of your previous answers, but is there a technical way to ensure, if social media users don't opt in, that the multiplication or pluralistic development of their individual data through their friends, their lists, their contacts, their friends' faces, can be prevented? Or does this come down to a matter of trust that the social media companies that users place their trust in will be true to whatever commitments they may or may not make now or are regulated to make in the future?
