Mark Zuckerberg: Facebook founder admits 'bunch of mistakes' amid privacy u-turn

Writing in a rare blog post, the social network site's founder and chief executive said he “founded Facebook on the idea that people want to share and connect with people in their lives, but to do this everyone needs complete control over who they share with at all times”.

But he added that while overall the site had a good history of being open about privacy, "I am the first to admit that we have made a bunch of mistakes".

He also admitted that the site's executives "can always do better" on the controversial issue.

His comments came after the US Federal Trade Commission (FTC) accused Facebook of systematically invading user privacy on seven specific counts, including when the social network had changed settings to make more of its users' information publicly visible.

The new plan to settle the compaints marks a major step on the social network’s road to its initial public offering, which had been widely expected to value the company at $100 billion.

Facebook will now be “required to obtain consumers’ affirmative express consent before enacting changes that override their privacy preferences”.

This will effectively make all major future privacy control changes opt in. Facebook must also submit to privacy audits every 2 years for the next 20 years, stop any access to content on deactivated accounts, and present its policies on privacy or security of user data more clearly.

Although new settings can apparently be added without requiring users to opt in, new services will now require users to explicitly give their consent if they are to take part. Facebook Places, for example, which allows users to check-in online to physical locations, was cited as an example of a service that Facebook would not now be able to turn on for all users without their consent.

Zuckerberg conceded that the site had made major mistakes with users’ privacy, citing the launch of the ‘Beacon’ system which showed users’ friends their shopping habits, and the company’s previous changes to privacy policies.

He claimed, however, that “When I built the first version of Facebook, almost nobody I knew wanted a public page on the internet. That seemed scary. But as long as they could make their page private, they felt safe sharing with their friends online. Control was key”.

Zuckerberg put the social network’s success down to making it “easy for people to feel comfortable sharing things about their real lives”.

“Overall, I think we have a good history of providing transparency and control over who can see your information,” he wrote.

"That said, I'm the first to admit that we've made a bunch of mistakes. In particular, I think that a small number of high profile mistakes, like Beacon four years ago and poor execution as we transitioned our privacy model two years ago, have often overshadowed much of the good work we've done.

"I also understand that many people are just naturally skeptical of what it means for hundreds of millions of people to share so much personal information online, especially using any one service."

He added: "Even if our record on privacy were perfect, I think many people would still rightfully question how their information was protected. It's important for people to think about this, and not one day goes by when I don't think about what it means for us to be the stewards of this community and their trust.

Facebook has always been committed to being transparent about the information you have stored with us – and we have led the internet in building tools to give people the ability to see and control what they share.

"But we can also always do better. I'm committed to making Facebook the leader in transparency and control around privacy."

The new agreement with the FTC “means we're making a clear and formal long-term commitment to do the things we've always tried to do and planned to keep doing - giving you tools to control who can see your information and then making sure only those people you intend can see it”, Zuckerberg said.

The social network will now also have two Chief Privacy Officers; former lawyer Erin Egan will be responsible for Policy, while Michael Richter will become Chief Privacy Officer, Products. Richter is currently Facebook's Chief Privacy Counsel.

Overall, the changes are set to alter Facebook’s development of new products, as well as its attitude to users. FTC Chairman Jon Leibowitz said ”Facebook’s innovation does not have to come at the expense of consumer privacy. The FTC action will ensure it will not.”

The proposals will now be put to a 30-day consultation period. They are likely to meet the majority of the concerns raised be European privacy regulators, although those issues remain unresolved.
