I dunno, I work in the cloud space, largely with fortune 500 companies, and I don't know of any off the top of my head that are investing in Azure.
That doesn't mean the article isn't technically accurate, of course, but I'd suspect that MSFT is being very generous with their definition of "using" and counting any pilot project in some engineering team as "using" - in which case I'm sure that most of the fortune 500 have someone somewhere playing with Azure.
But that's not the same as using from the standpoint that we typically think about it.
