Nobody said Nintendo doesn't care about this. What people are saying is this is no suprise to Nintendo. They'll have had the money set asside for this for a while and so it won't effect anything they might do now or in the future. As in they won't be saying: "Well we better not buy this dev house now since we got such a big fine" or "we better cut back our ad budget now to make up for that fine", this fine won't effect them.
But I'm certainly sure they care allot about it and don't want to pay it obviously, amd perhaps they won't, we'll have to see.
