I liked the way how Mark Polino posted about it in this post, checkout mark post below:
David Musgrave takes a look at Microsoft Dynamics ERP Licensing Changes. I’m going to say that on a personal level, there are elements of the new licensing that I find to be a naked cash grab by MS. Customers screamed about the DCO licenses and rather than deal with customer anger, MS renamed them to make them sound more appealing. Accessing GP data with other tools should be covered by other licenses, the SQL CAL, the Office CAL, etc.There is no good reason to allow access other data in the same location with these licenses but not cover Dynamics data. Companies have already paid for access to this data, there is no reason for them to have to pay again.
