I can tell you that when you're in a war in the Dev Clash you could have the stream on your second monitor and you wouldn't be able to pay attention to it. Not to mention KaiserJohan is one of the best players in the MP, while Norway and especially Portugal are quite new, with the latter only having 150 hours or so in the game, and this being the first aggressive player war both of them have ever started in a Dev Clash. If they were even able to listen to the stream while in their wars, it'd only have served to somewhat mitigate KaiserJohan's already massive advantage over them.
