It's actually opposite. I'm in the banking and financial tech industry. Google didn't want a piece of the interchange, they wanted your data - they are by definition a advertising company and would use transaction data to know what people are buying and leverage that. That was their business model and banks, who have their cardholders best interests in mind, rejected this business model. Apple, on the other hand, never knows anything about the transactions. It's a part of the Apple Pay random tokenization that occurs at the point of sale.
