Scribd Puts My Old Uploads Behind a Paywall and Goes Onto My Shitlist 16 years ago
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?
