May I ask why you are blaming AMD when it was your fault in purchasing a Motherboard that didn't have the correct BIOS version on it?
You didn't mention which Ryzen you purchased nor Motherboard. But most Motherboards will have on the cover that it supports AMD 3rd generation processors.
The company you should be blaming is the Motherboard's manufacturer or yourself for not researching Motherboards before buying one that didn't support 3rd generation processors with the correct BIOS version installed.
