All these attempts to re-define the word "public" are ultimately going to fail.
The bureaucrats behind this nonsense will be beaten back by unending criticism, resistance and disobedience. We can all play a part in harassing them, by waving our cameras around in plain view while taking photos; and if we're hassled, acting outraged and incredulous.
Eventually, legal action will end this. I'd like to see, for example, a class action suit on behalf of severely disabled people who can't go to these 'public' places, and can only see them via photos and web sites.
