I can imagine the journalist referring to all Matrix Codes as "QR".

This is it. All matrix codes are now commonly referred to as “QR Codes”. I’ve noticed this especially at airports where both passengers and gate agents refer to the “QR codes” on boarding passes. (Which are IIRC Aztec codes)

		Boarding passes are typically Aztec, but don‘t have to be. IATA allows other types as well: https://www.iata.org/contentassets/1dccc9ed041b4f3bbdcf8ee86...

In China the normal word is 二维码 "two-dimensional code".

is a barcode a one-dimensional code?

		Yes - even though it obviously has visual height the data only runs in one dimension. For the 2D codes like QR the data is in both directions, which is why orientation often comes up in their design.
