Well, here are a few quotes from the article that seem to target students who have more than a bachelor degree:

"So much so that, for some subjects, employers now require at least a Master's degree."

"I think CS and SE lecturers could learn a thing or two from me about writing good software."

"Many of the CS graduates I know suck as software developers, too."

"Hiring a computer science graduate for a programming role is, to me at least, like hiring a theoretical physicist to fix your car. "

"Just as there are countless CS graduates who have a theoretical grasp of compiler design but have never design a language or implemented a compiler."

Not sure if you're American, but "graduates" typically means "one who graduates from a Bachelor's program", at least in this context.

Most of your selected quotes are (probably) referring to programmers who only have a Bachelor's in CS.
