I don't know how Apple has evaded regulatory scrutiny for their refusal to sign Nvidia's eGPU drivers since 2018.
The government doesn’t care? They’re a minority of the market? The vast majority of their computers didn’t have slots to put Nvidia GPUs in, and now none of them do?
Apple doesn’t have a monopoly in any market they are in.
The same way Google evaded regulatory scrutiny for refusing to allow a YouTube client for Windows Phone?
They aren't a monopoly, hence why.
Evidence that NVIDIA has even been trying? My understanding is that Apple didn’t allow 3rd parties to write graphics drivers past 10.13, but they could’ve done a non-graphics driver like this.
