Re: That would be the 'Extinguish' part, right?
"publicly announced partnership where both companies stated as fact that Red Hat would carry out all support of their products on Azure personally using Red Hat staff in shared call centre facilities? "
I am guessing that you understand that Support != Operate != Developing a Product. :)
"There have been few if any vulnerabilities found in the other Azure services which were set up by MS."
By the same token that doesn't necessarily mean that there aren't plenty to be found.
