<SmellyHippy> Because Information wants to be free man. </SmellyHippy> I think its unreasonable to only allow one side of a story to be told. I think its unreasonable to want control of 3rd party conversations regarding your product. By all means, Rebutt to your hearts content, I'm sure $Vendor has more reach than $Blogger. This thread was started on the 4th of October 2013, on the 5th of October 2013, there was a Nutanix rep posting (who had an account here for a long time, but never posted). It's obvious companies already scour the web for references so they can control the conversation. So yes, I do believe these companies have time (and budget) for this. They don't need to get someone to publish a retraction, http://blogs.vmware.com/ and http://www.nutanix.com/blog/ exist, and could be used for debunking spurious claims. With such strict controls in place around conversations, it becomes increasingly difficult to find information regarding anything 'negative'. When you need to look at any benchmarking of VMware and Nutanix through glasses that have a 'This benchmark was approved by VMware or Nutanix' filter. Making decisions based on those benchmarks is far less than Ideal. If the product and/or service is good enough to stand on its own 2 feet, then let it. Until then, I'll regard benchmarks from those products with the same skepticism I regard Media releases from Inside North Korea (is Best Korea). .
