While I usually question the sincerity of the leadership of large ccompanies (whether they really believe what they are saying or if they are just trying to increase shareholder value). But it strikes me that Tim Cook, being a professional gay man of his age, almost certainly has had times in his past where privacy was a big concern. Especially during times when it was much less acceptable to be gay, especially in the corporate world. He likely intimately understands the reality of the "nothing to hide" farce.
