I don't think it's a sense of entitlement in this case. Why shouldn't people be upset when they would gladly pay to keep a service alive, but the silly creators decided not to let their customers pay out of some misguided hope for megariches? This isn't about getting something for free. It's about the way you feel when somebody you love makes the same criminally idiotic mistake, over & over -- no matter what you do or say or how you try to help -- and ends up really hurting themselves AND others. Like the whole Xmarks fiasco. The guy was totally against the idea of asking his customers to pay, and he had huge costs, so he announced he was going to shut it down. Then his users revolted to such a degree that he finally decided to accept payments. And his customers paid up. Result: Xmarks is still alive & appears to be thriving. It would have simply fallen off the face of the earth, forever, if not for its devoted users getting angry enough to act.
