Now wait a second.
The loophole allowed you to bypass the fee when the new travel date was within 21 days of the ticketing date.
The new rule here, as described (we haven't seen the formal language), would charge the fee when the new travel date was within 21 days of the change date.
That's a big difference. I'll bet it's pretty common for someone to book an award months in advance, then decide at the last minute to leave a day early or return a day later; probably much more common than the loophole-evaders.
