Take it up with the Archdioceses of Rio. I'm sure they give special permission to use the likeness occasionally but still. I don't see the exclusion as being detrimental. It can create a "learning opportunity" that will let people learn more about Brazil. Kind of like the tropicalia movement in the 60s and 70s did.
So you think they gave permission for it to be included in the Call Of Duty: Modern Warfare 2 map; Favela?
