| This may be a poor example, but Coca Cola has been available for over 100 years... But the "secret formula" has been kept secret until the last 20 years or so...
Even for a product readily available for sale, terms of business agreements, require non disclosure to protect the copyrights/patents/trademarks of those who choose to maintain their technology rights.
Hypothetically speaking, Nvidia created their chipset, and therefore has the right to protect it's technology. While they may want to tout it to the world to market it aggressively, they must also guard their technology from copycats. Personally, I'd love to know more. But I also respect the fact that, it's possible that someone knows the answer, and if that person disclosed it publically.... could lose their job. Also, the employer could be sued for breach of contract.
The buyer's right to know, is superceded by the technology owner's right to protect.
