I'm familiar with the timeline of events, it's just that this post title is intentionally obscure. As for why, it could be due to a recent enforcement by NVIDIA of a specific part in their EULA

Nvidia has banned running CUDA-based software on other hardware platforms using translation layers in its licensing terms listed online since 2021, but the warning previously wasn't included in the documentation placed on a host system during the installation process. This language has been added to the EULA that's included when installing CUDA 11.6 and newer versions.

The restriction appears to be designed to prevent initiatives like ZLUDA, which both Intel and AMD have recently participated, and, perhaps more critically, some Chinese GPU makers from utilizing CUDA code with translation layers.

My guess is that either AMD were directly contacted or preemptively closed off a legal loophole.
