If the chip was found by a contractor of Apple then Bloomberg has indeed asserted something that is factually wrong. But it is not a materially important error, and calling it a "new assertion from whole cloth" is severely overstating the magnitude of the error. If someone that is talking about bash called linux for "a unix", I don't think most people would support your stance that they made completely baseless statement.
