Sure, but even if you're technically right, for Word there's a million tutorials and YouTube videos if you get stuck, not to mention that basically every office seems to have "that MS Office person" who seemingly knows every single trick imaginable in Word. Even if Word is more complicated, it's relatively cheap and easy to unblock yourself. I've not used LyX, but I suspect that it doesn't have nearly the same level of domain knowledge in the corporate world, artificially making it harder to learn.

Is that fair? No, not at all, but that just seems to be how it is.
