I still can't use it and won't be able to, probably forever. I'm not on Facebook and I don't have plans to become part of that thing for the next two centuries or so, but a lot of people I happen to share the same geographical coordinates do. They take and upload photos at events thinking everyone wants to appear in their videos. Now imagine -as someone who strives every single day to stay away from that platform and all associated things- playing an instrument at a dinner and realizing there are no less than half the people there pointing a cellphone at you. How in the Universe can I ask people I don't ever recall the name not to shoot videos of me, or at least not put them on Facebook because once they do I can't ask Facebook to delete them because I don't have a Facebook account? The real problem here is that I am already somewhere on Facebook since forever although I firmly refuse to be part of it, and I have no way of telling them to delete all my data, short of making an account, which would negate everything I am struggling for. This is crazy. A while ago I proposed somewhere (probably here, can't recall for sure) a barcode which if shown (worn?) tells the system used to shoot the video that the associated human doesn't want to appear, so that the whole person is deleted from the scene. Now that the random-faces technology has progressed, I would add some AI that swaps that person with a fake one so that the photo won't be ruined by an empty area. In the meantime we could create human readable symbols telling if and how we want our image to be used and instruct people how to use them, then one day hopefully if someone posts a photo of me while wearing a patch/shirt/whatever with a crossed camera, I can force that person to delete the photo or sue the platform that keeps it online. Of course there should be exceptions for well known public figures and/or public officers during service (read: the heck I'm not uploading a photo of say police abuse even if the cop wears a 5 meters wide photo of a crossed camera!).
