I consider Google and Facebook to be socially destructuve institutions, and anything done to reign them in by law, or better yet cultural demand, is beneficial to society. In the USA, photography (or videography) in public will very soon become so restricted as to be functionally illegal. Already, and for many years now, police in every city I've lived "pretend" that public photography is illegal. For example, I've been stopped and held for ID check and questioning no less than 5 times while photographing public buildings. It happened enough that I began to carry the law on a small postcard to give to police to read (not that The Law stops them from harrassing you). Everyday in America you can find posted videos of police telling people they can't take videos of police or fire actions, or airports or jails or city halls and so on. So, regardless of the law, in practice, the police will make it very dangerous for people to use cameras in public. They of course have no interest in protecting the public, they are simply trying to avoid wrong doing caught on film.
