Of course there's something wrong with that. It is a fundamental
principle of contract law that you cannot be bound by something
you could not have known when entering into the agreement. 

If they tell you in advance "it's either GPLv2 or our proprietary
license; choose now and be bound forever", then it is your choice
and you must stick with it.

"These are my license terms. If you don't like them, I have others."
Apart from being a play on a very old joke, I don't see anything
wrong with it.
