Precisely. The ethos of the Facebook notion of sharing and privacy is antithetical to what a financial service needs to have. One big reason I trust Paypal for everyday transactions is because they make money off of each transaction directly, whether through direct fees or merchant fees. I can understand their business model, and the service has a certain simplicity. The OP wants me to give financial data to a company where my data is their product, and who is always trying to prise more "openness" from me through a byzantine privacy UI and borderline surreptitious app installations? I'll pass, thanks.
