Banasevic is far from being the first high-profile name to jump ship this year. His move follows the departure of two other top competition officials with long experience in fighting Silicon Valley giants -- Cecilio Madero Villarejo and Carles Esteva Mosso -- who also are joining law firms that act for the very same companies. Madero was the chief of antitrust within the Commission's competition department when Vestager launched her crusade against Google.
