The reality (in the US at least) is that a CS degree is sold as vocational program by the universities, and many jobs list a CS degree as a requirement or a desired skill. The author’s students paid almost $7000 for her course alone.
Well, it's very hard for me to have a discussion about philosophical merits of education when the context is the USA where education is so fundamentally fucked. It might as well be that the best course of action for the well-being of students is to make sure they at least get bang for their buck, but that's a systemic problem one level below what I'm talking about even. I don't want to discount this as a reality for actual people on the ground - I think then the correct position is not my waxing philosophical about contents of courses, but rather nailing everyone against free public education in the US government to a fucking wall.

This is, I think, a symptom of this push-and-pull between industry and academia. The industry would want to have a CS degree mean that they're getting engineers ready to patch up their legacy code, because they would much rather have the state (or the students themselves in the USA case) pay for that training than having to train their employees themselves. But I suggest that the correct default response to industry's wants is "NO." unless they have some really good points. Google can pay for their employees to learn C++, but they won't pay a dime to teach you something they don't need for their profit margins. Which is precisely the point of public education, teaching you stuff because it's philosophically justified to have a population that knows things, not because they lead to $$$.
