Fair point, but AFAIK those company don't bother unless big amount of money is involved (usually due to security concern) or user are forced to pay small amount of recovery fees.
Sure and that's understandable, same with making all sorts of mistakes when dealing with/sending altcoins/tokens, time is money and there's no reason for a company to waste and pay for their employees time every time someone makes a mistake and accidentally loses $20 worth of coins/tokens.
