I wouldn't say this is obvious at all. If Apple thinks gift cards are fraudulent, it shouldn't sell them or accept them as a payment method.
This is not accepting gift cards.
I guess you have experience of the former. Apple is engaged in the latter.
I expect the best that can happen is a small claims court victory thereby getting their money back, but not their software. And that might also be followed by a lifetime ban by Apple.
And you should only use your credit card at places where there's zero chance of it getting stolen (no US restaurants!), or getting skimmed, or hacked once it's in their system.
...Or perhaps we live in a world where things are not entirely black and white, and nuance exists?
