Not true (unless you mean w/o penalty). There are plenty of exceptions. There's a V fare for LAX-SYD that's refundable (with penalty). Taking a random route (NYC-SEL) o/w on a random day next month I see a <$1200 Q fare that's refundable (with penalty).
Heck, there's a refundable SEA-SEL S fare ($821, penalty).
All of these have a $300 charge for refund.
