While I generally agree with your points, I don't think they are particularly apt to this article. The guy isn't saying Scribd owes him anything, he even states that he understands they never promised him a free service in perpetuity.

But when you make a service available for free and take pride in that fact, harvest your users content, and then suddenly flip over to a paid service without even giving your users adequate notice or tools to opt out I can completely understand how users might feel cheated.

Isn't the company partly responsible for creating the sense of entitlement you're talking about?

I totally agree with you that it is understandable to feel cheated in this occasion. Changing the model without saying so clearly is just bad communication (see the posterous link fiasco). But nevertheless I feel that a company does not have to explicitly state the fact that they are somehow aspiring to make money with their product, that is a given. So as a user I cannot be too shocked when somecorp starts to make money.
