What exclusive materials or advantages do Microsoft "Partner" companies have thesedays? MS is very good at making available their documentation, and almost all of their modern stuff (.NET Core, etc) is developed openly on GitHub.
But other companies that aren't as engineering-driven like SAP, Oracle, yeah - I can see them doing that.
The only advantage I can think of is one of cross-promotion or referrals from Microsoft's own consulting division. (I'll admit I have no idea who MS's Consulting customers are - I thought everyone went with Accenture, IBM, Capita or Atos).
