"The article above hints that people modding games may have a stake in this - I don't agree. Botting isn't about modding, it's about unattended play, bypassing much of the games experience and required effort and it can ruin it for other gamers."
Problem is that the specific wording in this ruling means that it opens up the possibility to slam modders with DMCA violations as well. Diablo file editors, those playing SAMP or Multi-Theft Auto (GTA San Andreas was given a modkiller patch after the Hot Coffee incident), Doom 1 & 2 modders (I think Quake was the first one that officially supported modding) and others. Because this ruling means that any editing to any game code == DMCA violation.
As if the DMCA wasn't bad enough!
