I did a non-cs undergrad to cs grad path... It was hard. I wasn't admitted to the program without fulfilling almost all the core CS undergrad classes. This meant that between the prerequisites and the actual grad classes, I took over 120 credit hours of pure math and CS classes over the course of 5 years. Obviously not every school has the same demands as others, and there are certainly a lot of degree farms that take foreign students money and funnel them though, but I'm not sure that the authors points ring very true... certainly not for everyone.
