I cancelled Netflix years ago. I just got a new Shield TV remote with only a Netflix button and it is constantly getting hit. I probably hit it 5+ times a night. I wonder what they learn from that.
If that button makes 1 out of 10 people have a slight preference for Netflix, it still adds up. The real question is how much Netflix is paying NVidia to have it there.
Open it up and put a small bit of kapton tape on the circuit board beneath that button to prevent it from making contact. Then it will do nothing, forever.
