I think the author has somewhat conflated the concept of CRI and color temperature in the article. An incandescent bulb or a candle has 100 CRI because they are almost by definition close to the ideal. That said a typical incandescent bulb is going to be somewhere in the 2500-3500K color temp. Lots of cheap flo bulbs tend to be both relatively low CRI and have a color temp in the 5000-6000K range which is more like 'daylight without benefits'. They tend to have lots of blue and greens and nothing else. Lots/most LED lights fall in this range as well. My personal opinion is that lighting products should be required to list CRI and color temp, just like nutrition information on food. :)
