It would make much more sense to just use the data for advertising and not peoples pictures. Examples: - If you see Steve's close friends all drink grey goose but he doesn't start advertising goose to him - If you have advertised Polo shirts to John and then he uploads a picture of him in a new Polo shirt, fb can take credit for that sale - Allow advertisers to exclude users who already own/use their product etc. This approach is much less visible to consumers and so would be more widely accepted (or just have less articles saying bad things about it).
