Here we are - 3600 which was still under manufacture 2-3 years ago are not get patched. Shame on you AMD, if it is true.
The cost isn’t that high. They’re already doing it for a bunch of parallel systems.
In a just world they’d be legally required to provide the fixes, or fully refund the entire platform cost. It’s not remotely ethical to allow this to exist unpatched anywhere, regardless of support life.
