It sounds like Purplekow was okay with service charge and later surprised to learn of the service charge on the receiving end thus making the use of gofundme questionable. I think it's a perfectly good subject to raise and there is nothing gained in scolding him for his generous spirit.
BTW, if the fees are accurate I think it is a rip-off. I hope their website clearly states that the recipient only receives 70% of the donation amount.
