Lloyd Korn shuts down MapleStory hackers.

Having guns as a form of expression is not illegal. Shooting people is. Shooting cans is not.

Writing code as a form of expression is not illegal. Using it for copyright infringement is. Using it for cheating in a single player game is not.

You want to come up with a better example?

You forget , MS isn't a single player game. And expression comes at a limit. The minute you infringe upon the rights of others it no longer becomes expression nor will it be protected, but rather looked down upon.

Nothing wrong with writing code. But when that code disrupts the good hard work of Nexon and it infringes upon their rights and you blatantly yet deliberately use that so called "expression" even though you agreed to NOT use it, then it's not expression. It's just an annoyance, that justifies Nexon's current actions.
