Besides the hot mess that is Google's branding and app strategy for their (not only) payment-related products that I'm sure others will comment on:

I wonder what the business model was going to be here? Facilitating P2P payments in the US is anything but free, especially when done over card rails as Google Pay did, as far as I remember.

Were they sponsored by one or both of the networks initially (I vaguely remember hearing something about Mastercard Send, but that could have been Meta), and were they hoping they'd grow enough to keep those terms?

Were they hoping to find a business model along the way, maybe in combination with the abandoned banking project?
