Facebook announces intention to share users’ contact info with third parties

In the letter, Facebook says it will give users control over which third-parties have access to this information.

“If the user wants to permit the application to obtain the information identified, he or she can authorize the application. If, by contrast, the user is not comfortable sharing the information the application is requesting, the user can decline to authorize the application,” the letter reads.

Facebook says there is "a standard screen, presented to the user at the moment the user is deciding whether to authorize the application, which identifies precisely what information the application requires to operate."

In a letter to Reps. Edward Markey (D-Mass.) and Joe Barton (R-Tex.), who both expressed concerns over Facebook's plan to make such data available, company officials reiterated their now-familiar pledge to leave it up to users to decide whether they want their personal contact information to go out to app developers and outside websites.

Markey has previously said that "Facebook needs to protect the personal information of its users to ensure that Facebook doesn't become Phonebook."

The company, meanwhile, sounds as though it has no plans to trim back its information-sharing ambitions.

"We have not yet decided when or in what manner we will redeploy the permission for mobile numbers and addresses," the letter states. "We are evaluating whether and how we can increase the visibility of applications' request for permission to access user contact information. We are also considering whether additional user education would be helpful."

Facebook has incited user revolts in the past by arbitrarily re-calibrating its privacy settings and then making it difficult for even the most seasoned web geeks to figure out how to reset them. And once again, anger is roiling among tech industry observers.

"Facebook is the slowly warming pot of water and we, my friends, are the frog. By the time we noticed our peeling skin, another hunk of our privacy is long gone," MSNBC tech writer Helen A.S. Popkin wrote about the latest move. "This is how Facebook rolls: Strip away a huge chunk of your privacy, cry 'Our bad!' and roll it back when users and/or privacy advocates complain. Then wait awhile, and do whatever it is Facebook planned to do anyway. Voila! Boiled frog."

Or as Facebook VP Elliot Schrage bluntly (if less colorfully) put things in the midst of a similar uproar last year: If you don't want Facebook to share your personal information, don't share your personal information with Facebook.
