Ms. Day's remark is rather insulting. I just watched a video by Corey Yoder (Coriander Quilts) where she addressed pressing of seams. She usually presses to the side, preferring the "nesting" of seams over need to accurately pin to get them to match up. When there is a lot of bulk, though, she does press open. I fall into that category as well. usually to the side, for speed and easy accuracy, but open when it makes more sense. I don't really worry too much what someone else is doing.
