1 - One is "hacking tools", but that's described as using third-party or illegal programs. Manually updating Hackshield is neither.
2 - The second is straight-up called "modding", but that mentions changing the game files to play in a way that's not intended by the creators. And I'm pretty sure the creators didn't intend the game to not run at all, they intended it to be able to start up and log you in.
So yeah, no problem here, people are assuming too much, oh my god touching files is evil and will draw Satin (the dark lord of fabric) to you, etc.
