Here is another way to look at it: Would you to pay $10 out of your pocket to destroy $4990 of someone else's money?
The example above would be considered cruel by some. Yet the same people would argue that declining the deal in the first post is perfectly ethical.

That's not a good analogy. In this case, they know that their money hinges upon you accepting the offer. Offering an unequal distribution carries a higher risk of rejection, but higher potential for reward.
I don't see the problem with the analogy. In both cases, you are net $10 worse off and the other person is $4990 worse off. The ethics of the transaction are all a matter of perspective.
