It is a stupid claim without any qualifiers. It's not like people on consoles are choosing their GPU manufacturer. AMD is not so prevalent on consoles because people love AMD, Switch is not that successful because people love Nvidia.
So the old rule from the past decades still stands. Nvidia is the GPU maker of choice for you, AMD is the GPU maker of choice for your wallet.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
