Let me throw in a personal anecdote. I live pretty much in the middle of nowhere, in a city you've never heard of, in a relatively poor country. (The typical dev salary here is around $1k per month, 3× less that for juniors). Even around here, practically every IT person I know has some Linux experience. System administrators of various sorts have loads of it. Meanwhile, most have never heard that the BSD family exists at all, and almost no-one has any experience with it. Of course, it isn't representative at all of what happens in places that actually matter (like California..), but still.
