I'm in the middle of an argument with a pirate. Anyone want to help?

Hey, guys. I was hoping you could help me with a stupid fight I've been in on youtube for the past couple of days. The video is "Top Ten Scariest Free Games" And some guy asked why the uploader didn't include Penumbra on the list. (He didn't say which one. Just "Penumbra.")
I told him it wasn't on the list because it was not free. Then he said it was free for two years, and he got it free in the Humble Indie Bundle. He also said it was the game, NOT the source.
This isn't true, right? The game is obviously not free, and the Humble Bundle isn't either. I'd like someone here to support my argument, assuming I'm right.
