A lot of ABB policy like this puts host at disadvantage for retaliatory review.
I agree half the payment is more than fair. Ideally you would also want to stick to your cancellation policy, and other host might advise you to do. But ABB has recently changed their policy to allow host the option to issue full refund that puts host at even more risk for retaliatory review.
In the past, even a few months ago, guest who canceled before checkin same day have gotten a request to review. This happened to me, guest never messaged, had booked the night before, I got payout, reservation canceled before check in, but thankfully guest didn't leave a review.
If you get a request to review, and decide to leave a review, do so at the very last minute on the 14th day after the reservation, if guest doesn't leave you one. You are hoping this guest doesn't leave you a review. So if you do before he/she does, she will get a message that you left a review and can only read it if she leaves one also. So if you are going to leave a bad review where there was an issue, host try to do it at the last minute so once they get the message, time will have already expired for them to leave one.
You can use the search feature for more info in past discussion also, or how to challenge a review. There are quite a few landmines host have to navigate.
