It may seem like he's just crying about it, because that's how it comes off, but a lot of what he said is true. I admit, I haven't been to death metal shows in Europe myself, but from videos I've seen and the size of the crowds that attend, it's much better over there. Here a band of Malevolent Creation's popularity level probably struggles to make ends meet. I doubt that touring the US is financially viable for them and that's the same reason so many death metal bands don't tour here often. Also, I'd like to point out that he did not say they are going to stop playing shows in the US altogether, they're just done touring.
