I am not sure what you are talking about.
From Wiki:
"Just as before the Mazda 626 was renamed to Mazda6 Atenza, Ford continues to use the Mazda's G-series platform for the basis of a number of its CD3 platform coded vehicles, including the Ford Fusion, Mercury Milan, Lincoln Zephyr/MKZ, Lincoln MKX, and a range of SUVs and minivans. Ford also plans to offer a hybrid powertrain on the platform. The official Mazda chassis codes are GG (sedan/hatch) and GY (wagon) series - following the 626/Capella in its GF/GW series."

I know it is hard but:
1. Mazda 6 was first. It was a very good car.
2. Ford twisted Mazda's arm and got the rights to use the platform to develop their own "products".
3. Ford Fusion is a stretched Mazda 6 with Ford stickers applied to it.
Those are facts. You may not like them, but that won't make them disappear.
