Firstly I said "perhaps", secondly it depends what is meant by credit. Did the Stones acknowledge/give credit in interviews, with regard to the origins of many of their early recordings, maybe they did I wasn't looking at the Stones very closely at the time, maybe Godin thought they didn't. Obviously they had to "credit" the songwriters on the records, but let lets face it how many people took notice or knew who they were. The Spencer Davis Group and Jackie Edwards being a perfect example, who the hell knew who J. Edwards was at the time ?.
