What? The researcher that found it and wrote the article already posted a PoC that can be used to farm data from VMs in any VPS provider.

I would like to think that the likelihood of being able to find a juicy target using one of these specific CPUs and who would have explicitly not updated their microcode for this exploit is much much much higher going after end users on the web than by attacking organized VPS providers.

It's okay to admit you are wrong or don't have a working POC.
