The Legend of Zelda: Tears of the Kingdom leaked online roughly 2 weeks before it launched, and not surprisingly, plenty of people decided to download the title. Nintendo obviously wasn’t happy about this, and it appears they’re being more proactive than ever about the situation.
Numerous software pirates have taken to online forums to discuss their Zelda piracy being called out by their internet service providers. Some people who decided to pirate the game have started receiving emails from their ISPs with DMCA notices. These emails show that the ISP is aware of the file that was downloaded (in this case, Tears of the Kingdom), where it was obtained from and when.
Long story short, ISPs are watching (no surprise here), and Nintendo is working with them to make sure these pirates have their nerves rattled. Will that stop them from pirating software going forward, or will these people just take more secretive measures? Nintendo’s hoping for one outcome, but only time will tell which way things go.
