Oh, it’s not as one sided a piece as I and the title make it out to be. They do talk to several competent proponents of rent control. But I think the case against it pretty clear and compelling: it’s good for the people on the inside, and really bad for everyone else.
Edit: The opinions of Dubner et al are not anywhere near as clear as Penn and Teller. I’ve been listening for years and I don’t think I could tell you which way he votes usually.
