It says they have lot of credit losses:

The provision for credit losses is treated as an expense on the company’s financial statements. They are expected losses from delinquent and bad debt or other credit that is likely to default or become unrecoverable.

Is it basically the Apple Card is “too good”, so people are signing up, racking up debt, then not paying it off and the terms/interest are causing Goldman to lose revenue?

These stories don’t make any sense.
