If the competition is offering the same product for free and Nvidia are holding back the availability deliberately to force up prices (as a few people seem to think) Nvidia are handing sales to the other three manufactures and allowing them to under cut them.
This is a mass production market. You add the costs, look at the competition and price accordingly and hit full production as long as you can make sustainable profit. The only way any of these business plans make any sense is if Nvidia don't think Gsync will be a big seller or know they can't compete with FreeSync or plan on turning over low volume with big margins. The other possibility is if Nvidia run Gsync like they did with 3D and feel they might get some value from running the Gsync business at a loss.
