There is ample evidence that CA had no impact. They were charlatans trying to sell snake oil; IIRC the underlying algorithm was based on a simple factorization of a User x Likes matrix that did not have substantial predictive value. There is plenty to lay at the feet of Meta, but I've always thought the CA scandal was an overreaction.
