As planned, executives from Apple and Google appeared in front of a US Senate judiciary subcommittee on mobile privacy on Tuesday. Speaking on behalf of Apple was the company's VP of software technology, Guy L. "Bud" Tribble, who repeated some of the company's previous positions on mobile privacy. "Apple is strongly committed to giving our customers clear and transparent notice, choice and control over their information, and we believe our products do so in a simple and elegant way," said Tribble.
