Below is the single page advert PayPal placed in the New York Times.

It makes reference to the nude iCloud photos and Apple’s lack of security. Perhaps PayPal needs to be reminded of the huge eBay hack that was kept quiet for ages. eBay and PayPal are owned by the same people.
Meanwhile American Banks are fighting already to gain Apple Pay customers.
“It’s a healthy competition,” JPMorgan Chase marketing chief Kristin Lemkau told the Financial Times. JPMorgan Chase launched Apple Pay-centered marketing campaigns on the same day as the service’s unveiling, and similar campaigns from Apple’s other partner banks quickly followed.”
So in my mind PayPal should be extremely worried!
