I don't think jedberg said anything that implies the value is exactly $0.00.
Rather, jedberg has already found way more suppliers than he needs, all willing to supply him ads at $0.00, which makes that the equilibrium price.
Analogously, I would value oxygen basically infinitely high because I don't want to die. However, I would never pay for it because I can easily get it for free, and would laugh at anyone who tried to charge me for permission to breathe.
I think it's difficult in general for people to put a price on most of the things they get for free, just because they're used to getting them for free, and build their price intuitions on being able to get them for free.
