Just look a few pages back in the thread, where the user Menel explained what sets Apple Pay apart from other mobile payment solutions. It's nothing that other companies can't use, but Apple is leading the charge right now.
You keep saying there needs to be trust in Apple with financial information. But if you knew the details of Apple Pay you would know Apple doesn't store account information, nor transaction information. So there is no financial data to store to trust them with.
So even if they did get hacked again, what financial information is there to steal?
It all sounds so simple, doesn't it?
What could possibly go wrong?
