The reason for introducing the legal concept of a 'windfall' is so observers will not be mislead by those falsely claiming HashFast hasn't provided full refunds for the small number of Batch 1 customers who requested them.
Doesn't matter if you call it a "windfall" or not, BTC refunds for BTC purchases were the original agreement by HashFast:

Hi Jim,
Thank you so much for your patience while I got the answer for you, I greatly appreciate it.
The answer is if you buy Baby Jet for 51 BitCoins today and it does not ship, you will be refunded the 51 BitCoins you paid.
I hope that helps and hope you have a good weekend!
Thanks,
