As Facebook prepares to hold its annual developer conference this week, many businesses are objecting to how the company has limited their access to its users\u2019 information.<\/b>
\nSAN FRANCISCO \u2014 For years, Cubeyou made a business out of personal data on Facebook. The company had unfettered access to Facebook users\u2019 information, which it gathered up through quizzes and later sold to clients.
But three weeks ago, Cubeyou\u2019s relationship with Facebook soured. The mighty social network, which was dealing with a backlash over how it had not done enough to protect user privacy, cut off Cubeyou after a CNBC report said that the small data analytics company had misled people into believing its quizzes would be used for nonprofit academic research. Instead, the report said, the data was sold to marketers.
Federico Treu, Cubeyou\u2019s chief executive, told The New York Times that his company had done nothing wrong, and that it had followed Facebook\u2019s rules in disclosing that it was using profile data for both academic and business purposes. He said Cubeyou was just collateral damage as Facebook has overzealously scrambled to show that it cares about data privacy.
\u201cFacebook threw us under the bus,\u201d said Mr. Treu, who added that he intended to boycott a Facebook event for developers this week. \u201cFacebook became what it was because of us developers. Now they want to blame us for everything that has happened to them.\u201d
Facebook\u2019s relationship with its vast community of developers has reached a tense moment once more. Since news broke in late March that the political consulting firm Cambridge Analytica had improperly harvested the information of millions of Facebook users, the social network has made a series of changes to limit how much of its users\u2019 information can be obtained by third parties. Those shifts have had an unintended domino effect on many of the companies and programmers that relied on Facebook\u2019s spigot of data for their businesses.
Some, like Cubeyou, said they have been unfairly blocked from accessing Facebook users. Tinder, the dating app, discovered that its users were no longer able to log into the app using their Facebook accounts. Pod, a calendar syncing app, found that its users could no longer see Facebook events within their calendars. And Job Fusion, a jobs app that allowed users to see where their Facebook friends worked, announced that it was not longer able to offer its services within Facebook.
The fallout has cast a shadow over Facebook\u2019s annual meeting with developers, which was scheduled to start on Tuesday in San Jose, Calif. The event, which includes a speech from Mark Zuckerberg, Facebook\u2019s chief executive, is typically a major attraction for developers. But this year, half a dozen developers who had previously attended the conference told The Times that they did not plan to go because they objected to Facebook\u2019s policy changes. Others who planned to be there said they intended to challenge Facebook\u2019s leaders over the changes.
Facebook said it expected roughly 5,000 people \u2014 a record high \u2014 to be at the developer conference, which is known as F8. But the company also said it has tweaked the event with an eye toward data privacy. For example, the social network canceled the announcement of a Facebook smart home speaker to challenge Amazon\u2019s Echo and Google\u2019s Home amid worries that the device would raise more questions about the amount of data the company collects.
Ime Archibong, Facebook\u2019s vice president of product partnerships, said developers are \u201cincredible partners\u201d for the company, but also added that it must \u201cstrike the right balance between creating compelling social experiences, protecting people\u2019s data, and supporting an innovative developer ecosystem.»
Bhaskar Chakravorti, senior associate dean at The Fletcher School at Tufts University, said Facebook had to walk a fine line. \u201cThey have taken a blunt instrument approach, which is the right thing to do from a public relations standpoint,\u201d he said. \u201cBut now they need to reach out to developers and smooth things over.\u201d
For much of its history, Facebook has had a rocky relationship with developers. It has sometimes adopted policies to attract developers, including by opening access to its vast troves of user data. Developers, in turn, created apps that became emblematic of the Facebook experience \u2014 apps such as Farmville, a farming simulation game played with friends on the social network, which was made by the gaming company Zynga.
But developers are often at the mercy of any changes that Facebook decides to make. When Facebook clamped down on viral apps several years ago, it became harder for companies like Zynga to spread their games across the social media site. Zynga has since turned toward making mobile games and its fortunes have plummeted.
Facebook announced a series of privacy changes in early April. Under the new measures, developers can only see a Facebook user\u2019s name, profile photo and email address; previously, the could see more information, like users\u2019 Facebook posts. Facebook is also cutting off developers\u2019 access to user accounts if someone has not used their apps for three months or longer. That policy is intended to prevent developers from collecting information in the background for months or years after people stop using their apps.
Facebook also announced that it was investigating apps that had gained access to large amounts of its data in the past, and said it was conducting an audit of any company that it believed has shown suspicious activity.
Cubeyou got caught up in the dragnet in early April. At the time, CNBC reported that the company, which is based in Redwood City, Calif., had collected users\u2019 Facebook information for academic purposes and then sold the data to commercial firms without informing users. Facebook said it was conducting an audit of Cubeyou to determine if there was any wrongdoing.
Mr. Treu said Cubeyou fully complies with Facebook\u2019s requirements of disclosing the data it collects and what that data is used for. He added that Cubeyou strips out any personally identifiable information that it gets from Facebook. Cubeyou is simply being singled out as part of \u201ca witch hunt\u201d by Facebook, he said.
\u201cWe did everything by the rules, and we are ready to prove that,\u201d said Mr. Treu, who said his company has repeatedly reached out to Facebook to talk. \u201cThere is no way to talk to them, to find out anything.\u201d<\/p>\n
