I think GFM did a massive blunder by not declaring that they will immediately refund the donations. I can understand their practical considerations - it probably costs them something to refund, but they should have just eaten the costs. Instead, they made it look like they are seizing the money - which looks very much like breach of trust. If I give you something with the promise that you will bring it to my friend, and you decide you don't like it so you donate it to the charity, I'd be pissed. Yes, I know GFM probably has a 200-page user agreement that makes you confirm your soul and your firstborn belongs to them and you have absolutely no rights whatsoever, but nobody reads that and everybody has expectations how this works, and "we'll seize all the money and send them to a charity" is wildly outside those expectations.
