Evidently, it is not safe to post individual images on any platform that could be seen as an economically valuable database. What it makes of Facebook, is unclear, as the amount of pictures is still big but they're diluted by other content, yet Flickr is definitely in danger. Still, this seems to target the database owners, not the individual uploaders. BUS probably hasn't realized yet there is Commons.
The part about the authors' right to exploit new technologies goes in principle clearly against any kind of free culture. If, say, the rules about music had been set on 1960s, on similar basis one could infer that music in public domain on vinyls but not in digital form, because this is a new technology and though Bach is not around to gather his fees, collective society certainly is. Usually people think that if there is a new technology, it is open by default, the usual freedoms are extended to it; this decision says anything new is closed by default.
