Is this essentially going to be an investigation in which they find that which has made people butthurt is something they signed away in the terms & conditions they never read? Seems like it. Good on GoFundMe.
Alternatively, make the 15,000 tiny letters illegal, and require products to specify in clear, easily understandable language what the user is agreeing to; with the ability to return whatever it is if they do not agree with it.
But this idea of donating to other charities unless a refund is requested appears to be something novel. As far as I can tell, it's something they came up with, then backed away from, just for this incident specifically.
