but speculate why Capstan’s Co-Founder and CTO Jay M. Williams and crew wanted to join QTMM?
For one thing, what crew?
As for Jay, my guess is he didn't have much of a choice. I don't think he owned a majority stake in Capstan. My guess is that the guy who signed the bill-of-sale was calling the shots, and that he saw this as a last ditch effort to salvage something out of an investment that yielded no sales and that he didn't want to put any more money into.
I suspect Jay had a choice between CTO and unemployment.
