Flat SubD mode or box SubD mode?

Rhino 7 documentation says: The SubDDisplayToggle command switches the appearance of all SubD objects between smooth and flat modes. source: https://docs.mcneel.com/rhino/7/help/en-us/commands/subddisplaytoggle.htm

On the other hand, Brian James and Kyle Houchens claim that the flat mode is called box mode. source:

I call it flat mode. What is your opinion?

For people who used SubD a lot with box-modelling approach this is box mode. I am one of those, box mode it is.

Then again there was a time it was called crunchy.
