Apple credit cards allegedly giving men 10x the credit limit of women

I'm sure Apple is not so stupid and sexist as to have business logic that gives men 10x the credit limit as women, other things being equal. My guess is that the credit limit depends on the person's reported individual income, so that if the husband earns more than the wife, which is still true in the majority of U.S. households, he gets a higher credit limit. If that is the explanation, I think it's a plausible, non-sexist way of setting a credit limit, although setting a credit limit based on household income is equally plausible.

This is concerning, but the examples they gave were all from couples where the man contributed most of their combined wealth, AFAIK, might that not be the reason?

Is there an example where the wife contributed most of the combined wealth? What would their credit allowance balance look like?

Or what would happen if you just remove the gender variable from the algorithms?

This doesn’t seem logical. Women are responsible for a large chuck of house hold spending... why would a company such as Goldman Sachs want to limit their ability to spend? The less they spend, the less data they can gather on their spending habits.
