"Microsoft and have made their hardware a little more open and/or standards complaint, paving the way for open source drivers that can potentially be written for any hardware-OS combination."

I think the writer of the above does not understand industry standards. Industry standards are not whatever is most widely used. Industry standards are data layouts and protocols for interoperation so that there is as little lock in as possible.
It does not mean that Intel as the most widely used is the standard that vendors must use. That would forever keep the industry back. Standards should be as little prescriptive as possible,
