He's not able to sell it now, so it is essentially worthless. He is now trying to salvage his brand/reputation by this "noble" act. I say we should have longer memory than goldfish when it comes to issues like these.
He also used GPLv3 which Apple hates. They even stick with a ridiculously old version of bash (3.2.57 from 2007!) since it had since began using GPLv3 in subsequent versions.
Yeah, I'm not suggesting he's a saint or deserves a parade, but I am happy to have another real-world, full-wrap iOS project to review (whether it's well written or not, I don't know) or repurpose.
Edit: My point is: you say that it's worthless, and perhaps it is now to him, but not necessarily to others.
It's the details that matter. :)
