The point is that morality doesn't and shouldn't play into it. Usually companies don't follow moral principle but rather legal principle. Smart individual should do the same thing. Otherwise they are and will be abused and taken advantage of.
There is a middle ground of course. Not unbending personal morality above all else but rather a good faith effort to both stand up for yourself in safe ways and to stand by the interests of those who you want to stand by yours.
This is why I am not opposed to withdrawing acceptance of an exploding offer at the last minute. It's better for the employer and yourself if you quit then rather than two weeks into the job.
