It wouldn't, it is clear to everyone who understands how BTC works that tx fees attached to a tx is for the miners, and in the case of an overpayment the miner has the right to keep their reward in fees or return it if they want to, whatever they decide to do is up to them and is 'right'. Situations of huge overpayments rarely happens anyway, so what i think is that as this very case with Paxos was widely covered, it will teach people to use good wallets to make tx's and also to double check everything before broadcasting.
