It is not a good idea to lie when the truth is visible to your audience.

Maxwell did not say one way or other whether the speed of light is
c relative to its source. From what he did say we can infer that he
thought that that depeds on the motion of the source. Maxwell thought
that the speed of light is c in some frame that was later called ether.
Later Michelson tried to determine Earths speed in that frame but
failed.
