I'm not sure it's a contradiction either, more of an omission, he doesn't specifically address search data in that interview. However the comments are aimed squarely at Google so the PR message rings a bit hollow.
I don't find it surprising that they're collecting as much data as they can, it just seems odd to call out competitors who do similar things.
“Our business is not based on having information about you. You’re not our product ... I think everyone has to ask, how do companies make their money? Follow the money. And if they’re making money mainly by collecting gobs of personal data, I think you have a right to be worried.”
“We take a very different view of this than a lot of other companies have. Our view is, when we design a new service, we try not to collect data,”
“We’re not in that business. I’m offended by lots of it. And so, I think people have a right to privacy.”
