"AMD, too, seems unlikely to remain on this list in the future."
There's an update on that page that hints that the above may not be true:
"After The Reg went to press, a representative from AMD reached out to clarify the situation in Dresden. According to the email from AMD's Mike Silverman, the OSRC site has indeed been closed, but although AMD has not announced any specific plans, Silverman says its Linux kernel efforts will soldier on:
'...We will continue to support the Linux kernel, and the software development work happening at the OSRC is being consolidated and will be performed at other AMD locations....'
It seems, IMO, a bad business decision for AMD to drop most of its Linux development work. This quote implies, perhaps, that they realize that and don't plan to make that mistake. We'll see, I suppose, in a year or so whether these cuts were significant enough to take them off of the list.
