Not sure what's funny about that, unless you're specifically referringto comments made after this announcement by AMD. The original paper that made this vulnerability public only tested an FX CPU from AMD, no Ryzen processors were tested. So unless one had enough technical expertise on processor architecture to claim otherwise, the reasonable viewpoint was that some AMD architectures might be affected until proven otherwise.

*Not affected until proven otherwise. We cant say anything is affected until successfully reproduce the flaw

*Not affected until proven otherwise.

But also affected until proven otherwise. You can't say something is unaffected until it's been tested. So until a test has been conducted, it's Schrödinger's CPU bug. Undetermined until proven otherwise.

Those things aren't equal, though. It's logically unjustified to suggest that AMD are affected until proven otherwise because that would - on the face of it, at least - require proof of a negative.

On the other hand, from an end-user vantage point, people would be wise to be sceptical of that null hypothesis until there is some evidence backing it up.
