We can't fight China; it'd waste our time and they wouldn't even notice. We're not magically endowed crusaders for truth and justice; we're writers. Ripe targets are all well and good, but picking a fight we can win should come before picking a fight that sounds good.
The key thing is that we can win, and that is why they are ripe, because the copyright violation is so blatant.
Otherwise, there'd be no point releasing Wikipedia under the GFDL; we might as well do it under the public domain. The key thing is to keep our material free.
