It's crazy that outside sites have the ability to know a system's capabilities. That info should only be available if the user makes it available to be known, &, as the baseline, all connections to one's system should only know that there is something there capable of receiving data — with no restrictions on connections for systems that do not choose to unlock this or that info about themselves.
