I just reread the post you refer too. He never said the Charging Station was inferior. He just said it was currently located at GM headquarters, thus it didn't receive lease money from GM Headquarters. When this charging station gets moved to a dealer location, it would receive a lease payment from that dealer. Just sticking to what was actually written by Sass, your response to him is not correct.
Let's remember that it was publicly stated that the first "green zone" was at a corporate headquarters of GM where, unlike at the dealers, there is no lease payment. This unit was more of a "prototype" than the established current dealer model
