Am curious as to what the "public beaches" thing is in reference to (being as the links don't seem to be working in the original article): Some of the blows

Am curious as to what the "public beaches" thing is in reference to (being as the links don't seem to be working in the original article): Some of the blows have been self-inflicted, like venture capitalists who compare progressivism to Nazism or who block access to public beaches. I mean, I know that libertarian types (in SV and elsewhere) don't seem to put much stock in this "public property" concept, generally, but is there some particular local controversy they're alluding to here?
