Neither did I want to mock you or anything, sorry for perhaps coming off like that - so, we're good here
Anyway, I really see where you are coming from, I learned a lot from tutorials like this very one. I understand what you mean, but it is always about finding a middle way in texts like this. There's some basics you need to build upon if you want to do some in-depth explaining, or the tutorials would get overly complex. There's other articles about the plugin system, and even a section in the manual. If one had to explain that every time again, the articles would be cluttered. Finding this middle way is not always easy, tho, and you won't be able to need everyones needs
