They only really care about Linux usage in embedded computers (Jetson) and in datacenters, and Free drivers would allow you to modify them to permit using consumer GPUs in virtual machines. Currently, you need to spend significantly more money for an enterprise GPU that has the same specs as a consumer GPU just so the driver will allow you to use GPU passthrough. They did recently allow consumers to pass a GPU to a single Windows VM guest so you could run a Windows-only game, but you can't split access to the single GPU among multiple VMs.
