While this is true, if standard keyboards were bad then everyone who uses them would have issues, yet many (most?) don't.
Sometimes I think it comes down to actual typing technique. For example. I've heard of "Emacs pinky" which is easily avoided by simply using the Ctrl key opposite the key being pressed (use right Ctrl for C-c for example). I religiously never use Ctrl, Shift or Alt + another key with the same hand and I feel that's been huge. Also my elbow, wrist and hand always form a straight line to the keyboard with a standard laptop keyboard and the right body position/desk and chair adjustment.
