Don't get your hopes up.
This is a suit where one pack of wolves is suing another pack of wolves. One of them is going to try to blend in with the flock and shout down with the man, but in perfect Animal farm fashion, they are more interested fleecing sheep than the other wolves.
Be clear eyed about this, this suit is about breaking Apples lock on the devices so the incumbent payment processors can charge MORE than Apple, not less. The result of a win will look like progress. "look they have to allow other processors equal access to Apple devices, we are are equal now!"
Only some will be more equal then others, and the scope of this suit will leave out the fact that the incumbents have a stranglehold on the POS terminals and card readers. So once they can force their way onto Apple devices, they can disable support for their competition on the device on the other end of the transaction. Any settlement that does not address equal and open access to both the device wallets AND the merchant side hardware, contracts, and fees will just be opening Pandora's box. I had a long conversation with the owner of my favorite sandwich shop, and he was hurting pretty bad. One of the reasons he was on the ropes was the shift away from cash during the pandemic, and the sky high fees on square, cash app, and the older CC merchant networks.
To be clear Apple's own arguments are disingenuous and self serving, but the fees they are asking for are TINY by industry standards. Unlike the App store, this isn't about Apple being the sole operator of a rent seeking cartel, it's about Apple breaking into someone else's.
