Completely right - its not a Microsoft problem as much as its an "enterprise" problem. IT Managers love things like SOAP.
And they should. It's easy to turn a WSDL into an exhibit for a contract, because it is a description of an API that can be converted to human readable and machine readable formats. There is no equivalent for REST, and most REST services have a loose interpretation of what it means to be "RESTful". Try doing serious, paid-availability integration with REST and watch the managers tear out their hair and the lawyers weep.
