Did you read my post? I said it right there.
Did you read the article? It says "rouge" more than 0.01% of the time, versus "single".
Have you noticed that the majority of the articles that discuss taking away the one-point, it is referred to as "rouge"?
(All these are rhetorical questions.)
I suppose one reason for using it is to avoid confusion with a punt single.
That kind of raises another discussion. If they ever got rid of the missed FG point, then what about the punt single? In the CFL, they can also punt it through the uprights for a FG, I believe. "It's not a missed FG. I's a punt into the end zone, so give me that single point!"
