"I view this as simple ethics. You keep your word, period." In general I agree. But what is the limitation? "I will work for you" is filled if you quit half way through your first day on the job and that's far worse for the employer than if you bailed out in advance. "If a company rescinds their offer due to no fault of your own (e.g, misrepresentation), then it's just as unethical as you rescinding your acceptance of the offer." I am going to say here that someone giving an exploding offer based on when you say your other interviews are is at least guilty here. I would argue that if someone does this, they entirely deserve what they get.
