Let's pretend I'm the greatest DevOps software developer engineer ever, and I write a Kubernetes replacement that's 100x better. Since it's 100x better, I simply charge 100x as much as it costs per CPU/RAM for a Kubernetes license to a 1,000 customers, and take all of that money to the bank and I deposit my check for $0.

I don't disagree with the rest of the comment, but the market for the software to host a web app is a weird market.
