The touchpad is the touchpad, i.e. another term for the trackpad. It's called the touch bar because the name touchpad was already taken by the thing below the space bar. "Touchpad" isn't some weird marketing term, it's probably a more common term for "trackpad" than "trackpad".

Besides, neither you nor I nor anyone reading or writing anything on HN is a normal user. If you're not a little butthurt by people using the wrong technical terms for things, you are in the wrong place and/or the wrong line of work.
