The article you point to illustrates that that basic attitude and culture is under threat. I agree. Openness, being able to build on the works of others, and learning "how something ticks on the inside" are still basic to science though.

I, too, wish that what the article illustrates weren't happening, but are you really arguing that you can't take the idea from a published paper, understand it and build your own work on it? The FOSS philosophy is the closest equivalent for code.
