An attack on the title: what the author does not realize, is that plumbing is not limited to the person who comes to their house to fix pipes. The majority of plumbing is from some water source to cleaning facility to your house and then back to treatment facility and finally back into nature. And that major part is actually mostly managed by "patricians".

Not that I support tech giants invasion in private lives. But when thought through the analogy works against the author's favor.
