Here's them falsely claiming they are an official Valve contractor (conversations with Valve contacts in my network denied this): https://redgpu.medium.com/redgpu-is-now-an-official-valve-co...
I pointed this out to show that you can't verify who is a Valve contractor and who is not, because that's how Valve can get away with stealing Microsoft's intellectual property.
So yes, I am a Valve contractor. (conversations with Valve contacts in my network confirm this)
