The complaint was that AMD was insignificant, not that it's low margin which is a perfectly acceptable business strategy.
As dralley mentioned. AMD is actually one of the few businesses with both strong CPU and GPU expertise. Building a console with any other company would require buying the CPU and GPU from two different companies. Intel would refuse and ARM CPUs including the ones Nvidia designed are not powerful enough, so really AMD CPU+Nvidia GPU is the only alternative to AMD CPU+AMD GPU but there is absolutely no reason for AMD to collaborate with Nvidia. The truth is that AMD is the only one that can serve this market.
