I don't know, the assertion in the article makes little sense. The white part shouldn't play any role at all in this; easily reversible male contraception has been a dream of many for a long time. These companies want to maximize profits, and it's obvious that they aren't limiting their products and procedures to what they as middle-aged men would want. If they were, there'd be no products or procedures for women. I think it's far more likely that these companies don't want to fund trials as it won't be nearly as profitable to them as current contraceptive options. If this was a pill instead, I have no doubt that the companies would champ at the bit for it. I think it's not coincidence that they could only find a non-profit to fund the trials for this specific product/procedure.
