I'm probably going to get flamed for this but I think even for it's time, it's wrong on a few accounts and it stinks of elitism and an "I am better than thou" attitude rather than a discussion on relative merits or the preface which was slapped on to change the context. It sounds like it's written by someone who's comfortable status quo is threatened.

Ubiquitous readily available knowledge is power, not elitist hackerism...
