I direct your attention to the footer of the page, which says:

My experience of working with fiendish teat-touting oligopolists is that the folks at the coalface are just folks. Google engineers: just folks. Microsoft engineers: just folks. IBM, Red Hat, SAP, Heroku/Salesforce, VMware: all just folks.

Most of the nonsense comes from upper managements, so far as I am able to determine.
