Ask HN: Does Apple Repair Butterfly Keyboards for Free?

Asking because my warranty expired 2 years ago, but over the last couple of months, I have had several buttons give up on me. And it's getting to the point where I feel like the keyboard is becoming unusable. Has anyone got experience with repairing their butterfly keyboard out of warranty? Did you have to pay for a replacement? Apple Live Chat was very defensive about this and didn't want to give me a clear answer.
