If they can simply change the key needed to sign the bios or whatever for new cards coming off their production line they can continue to support cards that were sold before the change and have the limiter for cards made after the change. They could also make a tiny to change to the model number. I don't see how they could possibly be sued for doing so. Nvidia is making the same money regardless if a miner or gamer buys their existing cards. They won't be losing any money of 100% of their production goes to gamers. As a game er if this reduces miners interest in the products I want I'd say it's good for me.
