The criticism is that it's not honest. "For free" is not correct. It's "book against harvesting your contact data". If that's what the first page would say, then it would be honest and nobody would be upset. But acting as if it's been "published" out of pure altruism is just misleading people, and they are righfully pointing that out.

Would you pay money in lieu of providing your real email address? If so, how much?

[gbear605]

I’d probably pay $10, that’s worth less to me than my contact info.

Just use a throwaway mail, what's the big deal? Companies already have tons of your private data without you ever even interacting with them. You're just crying into a 50 gallon drum of milk.
