Why is it shocking? It is a well documented fact that people very rarely donate $ to open source project they use daily. And if they do it is typically a very low amount.

What is shocking to me is that people give away their work for free and then get upset when they have financial problems. It should be kinda obvious that one leads to the other. Except in unusual cases (Linus for example).

Yes I agree it would be nice if that was not the case. If people were always generous and always did the right thing. However that is not how people operate in general. Pretending otherwise is crazy.
