Using whataboutism to deflect a claim of hypocrisy is wrong, I'm completly with you on that. However to be even more firm about this, regardless of the intentions of whataboutism, you can't hold citizens of a country responsible for the actions of their government unless they were directly involved.
However... visa V mastercard , using whataboutism is valid in this situation. Bringing up something the US government did in the past to silence the criticism of a US citizen to another countries actions is wrong.
EDIT: Just another thought about your example. There isn't even hypocrisy. Person B lent money to A and A paid it back, then Person A lent money to B and B didn't pay it back.

- B doesn't pay back money
- A pays back money
There's no contradictions in their actions.
