It’s a comparison, that luckily for Nikon, none of their customers are making.
In 2009 Canon introduced a disruptive technology. His name was the 5D Mark II and it was the devil incarnate. At the time they had a pro line-up of video camcorders like the XL2 which were used by filmmakers all over the world. Canon’s 60+ year old management probably thought they’d just killed an entire business, by accident, with a consumer DSLR.
