The UK's Digital, Culture, Media and Sport Committee is using this is an example of Facebook's anticompetitive nature, which is further highlighted in more of the internal files. In November 2012, in an email about reciprocity and data value, Zuckerberg talked about how Facebook's goal was to let people "share everything they want." Developers on the site, he said, could build apps to let users do exactly that, but Facebook needed to be wary of them becoming a competitor in the social media space.
"Sometimes the best way to enable people to share something is to have a developer build a special purpose app or network for that type of content and to make that app social by having Facebook plug into it," Zuckerberg said. "However, that may be good for the world but it's not good for us unless people also share back to Facebook and that content increases the value of our network. So ultimately, I think the purpose of platform -- even the read side -- is to increase sharing back into Facebook."
"I just can't think [of] any instances where that data has leaked from developer to developer and caused a real issue for us. Do you have examples of this?" -- Facebook CEO Mark Zuckerberg
Although Zuckerberg may have changed his views on the world since then, it's clear that at the time all he cared about was what was good for Facebook and not anyone else. But that's something he's probably thinking more about today, as his company continues to face scrutiny over its mishandling of user data -- especially after the Cambridge Analytica data-privacy scandal from earlier this year. In 2012, however, Zuckerberg dismissed the risks of sharing user data, since it seems he couldn't imagine that the incident caused by Cambridge Analytica was even possible.
In October 2012, Zuckerberg sent an email to Sam Lessin, Facebook's former director of product management, to say he was getting "more on board" with locking down some access to developers on the site, including Friends data and email addresses for mobile apps. That said, Zuckerberg told Lessin he was "generally skeptical that there is as much data leak strategic risk as you think," and that he agreed there was "a clear risk on the advertiser side" but hadn't figured out how that related to the rest of the Facebook platform. "I think we leak info to developers," Zuckerberg added, "but I just can't think [of] any instances where that data has leaked from developer to developer and caused a real issue for us. Do you have examples of this?"
