I didn't say Kyle solved Mongo's problems, but that he helped solve the problems. He identified numerous data loss issues, explained them in great detail, and even has tooling to readily reproduce the data loss events. That's a massive contribution in my mind. By comparison, it's the difference between a bug report that says "you lost my data, you suck!" and "I've identified [x] ways your product can lose data and here's exactly how to reproduce each one."
