Nintendo has such a thorough history of anti-consumer litigation that they have a Wikipedia article dedicated to it.

No, they didn't break down the doors of individual gamers. They targeted retailers and producers instead. They introduced DRM in their hardware. And with the rise of the internet they HAVE been breaking down the doors of people who make tools to extract the software from their cartridges. Even after emulation was established as legal in the Sony vs Bleem case, Nintendo continues to use their money and lawyers to bully emulator developers. They famously sent DMCA takedowns to people who made Let's Play videos or streamed the game, or even speedrunning videos.

Speedrunning events have had to cancel or ban Nintendo games because of their legal actions. Nintendo has taken legal actions against tournament organizers for competitive multiplayer games.
