I think that's fair but it also depends on the product. Something like Stripe, per transaction is a very obvious variable metric--and, even better more transactions is almost certainly a good thing for a merchant. A metric based on MB transmitted or API calls would be pretty silly.

AWS is inherently much harder to tie to non-technical measures. Yes the customers are more technical but that doesn't mean AWS formulas are necessarily predictable for them.
