First of all, it's not because x [1] and y and a bunch of others say that "a == true", you can safely use it as a fact or a way to support your view (those logical fallacies are called Bandwagon Fallacy/Appeal to Authority).
Second: I don't know where those code samples come from, but that is not exactly how you write good C++, as it is called in the paragraph. And a paragraph lower there is mention of the dreaded C/C++ - a thing that does not exist, never has, and never will. Some might say that adds to the author's points (as in, it's so hard he doesn't know how to write it properly), but you might as well say: sorry, but if you don't know how to write it properly then you do not really have the bagage needed to start criticizing it let alone calling it a monster.
[1] esecially when x is called Linus and he's in one of his rage moments where every single being that does not think alike is violently insulted and reduced to the dirt of the earth, with or without arguments making sense :]
