Hilarious. They're just people exercising their freedom. It's their computer, they can hook into the game's code if they want. I bet many of them are themselves hackers, worthy of respect. I bet many of them post here. When I was a kid I remember seeing people in forums who hacked games to make them harder because they played the shit out of it and were bored already.
These corporations? They are merely guests on our systems. Every single thing they think they can do? It's because we allow it. We allow their game to run at all. We refrain from modifying it. Everything they do, it's a privilege and we can revoke it. Ruin their PC? Good luck with that. If people care enough they'll reverse engineer your game and make their own version without all your bullshit.
