It always rubs me the wrong way when a customer decides what value something has to a business, assuming they know everything about the business' incomings and outgoings, assuming they know the size of the business, assuming that all businesses must operate the same way because some businesses have the flexibility to offer acts of goodwill.
It makes the assumption that all businesses, especially in software, are on equal footing. They very much aren't. Sorry, but the customer can't always be right — the business has its own bills to take care of, employees to pay, rights to licence, and lights to keep on; beyond what the customer paid for, it really doesn't have any further obligations. Good will is exactly that: good will.
