Also, an article can be read at the pace of your understanding. I'm not sure what my answer would be in a lecture, but I think it might switch. Wasting 100s of hours of time explaining something dull and trivial v's than leaving people with something to puzzle out in their own time, especially if they can ask you questions on it, is not so clear cut.
Conciseness around subtle points is a disaster in a lecture - you can't pause the lecture to take as long as you like to figure it out. Worse, if you don't get it, the rest of the lecture might be incomprehensible even if actually all follows in relatively simple ways from the subtle bit: the point where I start taking things on trust tends to be the point that I look track, IME.
