Has nothing to do with a suit from the original supplier. He's screwed no matter what.
That doesn't mean customers wouldn't inundate summit with returns and even returns of spurious origin, or begin dragging their name. It's a calculated move. Goodness of heart has nothing to do with it.
Besides, Summit probably has more to do with the revenue trajectory of speedmaster than most suppliers. In 2-5 years I bet 2/3 of the knockoff junk sm sells will pop up under summit's in-house brands, just like their knock off distributors and knock off msd boxes.
