I find it unethical because the net effect is that companies stop offering friendly return policies. When people treat return policies by the letter of the agreement rather than by its spirit, they create a world where companies won't offer relaxed return policies, and therefore make the world a bit worse for everyone else.

It's not illegal to use the agreement in this way, and I would never try to make it so. But I would absolutely look down on someone for behaving this way.
