I think he meant "hate" is too strong of a word. My impression is it just didn't serve much of a purpose for most people. I almost never use the function keys for anything but volume control anyway, and probably wouldn't have used the touch bar for anything but that either. It was just a waste. I probably wouldn't have hated it if I got one, maybe even found some nice uses for it, but I still think it was the right choice to get rid of it.
