Still don't get it. Because it's the same issue American have.
Americans want to Pb and nobody is there. No fight for them. In order to get a fight they have to wake up early or don't go to work. But I don't hear much complains by US players while they play as team in their alliance.
The only difference the Dutch British US alliance has a bigger variability in timezone. So when one nation goes to bed the other takes care.
