I think his point was that his company was willing to pay extra just for linux support. So Hauppauge was able to charge more money, and still get his custom. Whereas the companies that didn't support Linux didn't get his business.
From a business point of view, if the money that a company loses because of their lack of linux support is greater than the cost of opening the specs or writing the drivers, then the company should write Linux drivers. The poster was providing anecdotal evidence to indicate that they believe that this is the case for some (most?) companies.
On a personal note, I think companies perceive the cost of opening their drivers to be far higher than it really is.
