Arguably, merely storing a photo of someone is 'harvesting biometric data'. Comparing photos to one another to see if they match is hardly nefarious. Paradoxi

Arguably, merely storing a photo of someone is 'harvesting biometric data'. Comparing photos to one another to see if they match is hardly nefarious. Paradoxically, it's probably irrelevant: it doesn't help them make money in ads, it probably has no otherwise material effect on the service. I'm glad someone is suing FB but I'm not sure this is the right angle.
