Completely dishonest and backed by no fact at all, you can make up some data, I can too, I didn't. You call them "useless keys" but there are here for a reason. There are so useless than the touchbar can emulate this "useless" row, except that now users have to look at the keyboard to type since there is no physical feedback to guide them. this isn't innovation, this is a step back.
