Yeah, massive disagree with this. There is absolutely nothing "simple" about these protocols. Try to compose 3/4 UNIX programs together and you necessarily need to run it to see if it even makes sense. Don't get me started on HTTP.
It boils my blood to read "simple" in the context of software engineering
