Your entire insane rant falls apart right at the very beginning:
"Nutanix is lock-in simply because it's a proprietary stove-piped solution. Your data sits in a silo in a data format inaccessible by tools and protocols other than what the vendor allows you"
Nutanix uses the same formats the hypervisors use. There is nothing proprietary about the "data formats" at all. There is nothing preventing you from very easily moving from Nutanix off to someone else.
So basically, you're just making shit up. The question is...why?
