I believe the point is that if you want to play with it, your only choice is piracy, not that you must pirate it.
Since, in practice, nobody's going to pirate it either, that means there's no way to learn about it on your own. That's shutting down a very big free training mechanism for IBM, though it's probably too late to do anything about that now.
Karunamon didn't imply it to be fair game, he stated that it's too expensive to afford for learning for most people, which seems to be a simple fact. He also stated that it's a shame, which can mean either that it's a shame that you can't learn, or a shame that you're to infringe, and if taken to mean the latter that makes it seem like you're actually in violent agreement with him.
IBM can do whatever they like with their IP.
