The nice thing about a concrete example is it collapses hypotheticals.
Cambridge Analytica illegally deployed foreign workers to American campaigns [1], used improperly—perhaps illegally [2]—obtained data to target voters with messages that were at times conflicting and generally designed to inflame disagreement. CA took active measures to conceal they were behind these messages and takes active measures to conceal its own backers. Its (now former) CEO is on tape [3] attempting to sell services which violate the FCPA [4].
We need a solution that preserves Internet freedoms while protecting against this.
