I don't know about this "sales person" stuff, but I spoke with Chris Williams at length about GIBs(I use a heavily modified one), and the whole scenario, at the NC custom knifemaker's meeting, and he was not only totally respectful, and professional, but he also had nothing but good things to say about Jamie at Polar Bear Forge.
He didnt even remotely claim that the EERF was stolen to make the GIB, he said in fact that there had been amicable dialogue between themselves and agreement.
He acknowledged the obvious design limitations of thr eerf/gib that I pointed out and was open to discussing ways to alleviate them, and helped me make decisions on changes to my gib.
He is frankly one of the nicest and most open knife and tool makers I've ever met, and seemed to treat everyone with the same courtesy and respect so I have no clue what all this is about.
He's also returned all my calls and emails, even though he knows all I'm not likely to buy another grinder ever again when I can build one fron scratch.
