Yes, because the almighty Blizzard saying they are suing for infringement makes it so! Clearly you are not familiar with the absolute stupidity that is our legal system with regards to copyright infringement. In order to infringe a copyright, you have to use their code and/or game assets. These bots read memory and inject (DB) or physically control the mouse and keyboard. Neither of them need Blizzard game code to do so.
I'm not saying Blizzard can't sue. I'm saying this has ZERO to do with copyright. This is an example of what is wrong with this system. They are leveraging a previous precedent to hit a bigger bot. You think this is good because you hate botters, but you are ignoring the bigger picture that is the problem of fraudulent infringement claims. If they wanna sue for damages, go ahead! You can't prove it in this game! WoW....yeah, you can probably prove it due to the way gold sales and farming messes with their economy.
This is NOT infringement.
They used Blizzard assets on their website, they were removed a while ago however. They also use other trademarked/copyrighted material to sell/advertise their own product (without the required permission).
The "code" isn't what blizzard is claiming copyright infringement for.
