that’s really silly to argument. only a few manufactures in the world even have the capabilities to produce GPUs and CPUs. even China doesn’t have the fabrication capabilities with current generation. So of course, Valve is going to purchase GPUs from a 3rd party unless you expect them to spend tens of billions of dollars to start their own silicon fabrication…but oh wait, now they have to purchase silicon, so they’ll start their own silicon mine… but now they need trucks…so they start their own truck manufacture…
