There seems to be less sharing of "system level" code today when compared to the "days of yore". Part of it may be that the interfaces today are much more difficult and so there are fewer who truly understand them. Or because the knowledge itself is now considered "Intellectual Property" and must be restricted and "monetized". Or maybe because people are afraid that some nitwit will end up suing them when they can't get something to work and need a scapegoat. Today's society is "nastier" than the past about this sort of thing. Hopefully, the main reason is the first one. This whole thing is why I love Linux and FOSS in general.
