Why Google keeps your data forever, tracks you with ads

Not many companies could get away with defending controversial data retention practices by saying that the data is needed to "learn from good guys, fight off bad guys, [and] invent the future." But that's how Google sees itself and its practices -- not surprising from a company that would give itself an unofficial motto like "don't be evil."

Anderson had the chance recently to sit down with two of Google's top privacy people: deputy general counsel Nicole Wong and security/privacy engineer Alma Whitten. While the "good guy/bad guy" and "don't be evil" quotes may seem too cute by half to some, Wong and Whitten made a strong pitch for the truth of both slogans. In their view, Google really is fighting the good fight when it comes to your online privacy.
