While I agree that many are sloppy with macro and other related terms, I'm not sure there is enough standardisation to permit getting the trading standards authorities involved.

Otherwise, lenses like the Mamiya RB67 140mm macro lens (which requires extension tubes to achieve more than 1/2 life size) would have to be renamed, despite its excellent flat field performance and ability to be used with extension tubes for greatere magnification.
