Facebook bends to Europe's will, disables facial recognition (for now)
Found on Ars Technica on Friday, 21 September 2012

Facebook has come under fire in the EU for using facial recognition software to identify the people in users' photos and suggest friends to tag in those photos.
Facebook isn't giving up on facial recognition in the EU forever. In a statement sent to TechCrunch, it said, "It’s worth us reiterating that once we have agreed [on] an approach on the best way to notify and educate users with the DPC, we hope to bring back this useful tool."
Just make the feature an opt-in and let the user decide. Facebook has that ugly characteristic to enable every new feature per default for everybody, messing with the settings of the users. Almost always, this means less privacy.
