It's right in the article: "the use of the word “nurse” in the bios of CFN’s founders and the group’s name itself lends a misplaced impression of credibility." Also: ""It's dangerous to put that title out there, meaning a nurse title, which obviously carries meaning for the public and then misrepresents truth or science," Villeneuve said."

Misplaced credibility != using nurse to mislead.

Finally, the subtitle of the article suggests that those behind the group are not actually nurses.

How can you say that when they literally call them nurses.
