People seem to be making arguments based on principal which is fine but i don't quite understand the concern.
I played MW, I have no idea home many maps there are because I think I have only played 5-6 tops. The same maps always come up in the rotation. Perhaps its the mode I play but I know there's more maps than that.
Other cods were the same. Nuketown, the map with the boat, terminal, crash, High rise, firing range
