Counter Strike clone rips-off Dust2

Arctic Combat gets a little Dust-y with its ideas

I don't really see a problem with this, Valve didn't make Dust2, it was fan made, so they in fact stole the map themselves. Even then it's not stealing or infringing or whatever since you can't patent map layouts (at least not yet), nor would you ever want that to be the case.
