Largest Maplestory hacking website being sued by Nexon America and Nexon Korea Corp.

Er no. If that's true then Microsoft would be able to sue anyone who writes software that runs on Windows.

And they can.

Doesn't mean they do. The agreement that seems to be in place is that Microsoft allows people to create programs for their Operating System, as long as it doesnt

A) Modifiy the Source code in such a way that it could create a security risk
B) Does not infringe on any existing copyrights for what Microsoft already has in place
C) Does not contain malicious code etc...

But again, that scenario is pointless, because it doesnt apply to what nexon is doing.

Nexon is trying to IMPROVE their game. Are you trying to say that the hackers should be allowed to do whatever they want without any form of reprocussions?
