It's not about the PDF copy having zero marginal cost. Manning is a business that is trying to offer an incentive for customers to buy direct from them. Are you suggesting that they destroy their own value add?

Also, I seriously doubt that Manning responded to d0m's request by literally saying:

"Fu, it's your problem, next time buy it at manning, not amazon"

Pronounced "F-U" and not "foo".

The moment you twist someone's wording to sound that aggressive, you're overreacting.

I don't know if I would consider emailing a PDF to a customer who made an honest mistake "destroying your value add".

I've given some paid members on setformarriage.com free lifetime accounts because they were consistently forwarding us emails from the spam profiles that made it through our filters. I think the value of overall goodwill to the customers is probably worth it.
