Silicon Valley, not Washington, needs to lead on privacy reform

[Commentary] If the largest US Internet companies want to win back the trust of consumers who care about online privacy, they should start not with appeals to Washington but with reform of their own data-collection technologies and practices. That data has helped boost their sales yet made users vulnerable to secret surveillance. Surely an industry that invented everything from Internet search to the sponsored tweet can develop better ways to keep user data safe -- if that's indeed one of its primary concerns. Whether it is though remains an open question after public statements made this week failed to mention several key facts about why secret National Security Agency surveillance is hurting their industry's reputation.
