Ok, that makes a bit more sense then.
eGPUs got pretty good support on Intel Macs in the years leading up to Apple Silicon. And that transition started 5+ years ago. And now all Apple Silicon Macs have no eGPU support.
I find it weird that you cite eGPU support since hackintoshes almost always have PCI slots. And the eGPU support still comes from Apple (at the driver level) even on a hackintosh. AFAIK.

lol, this totally makes sense to me. It can’t be the only reason. But my lived experience tells me it’s not insignificant.
