On a related note, exploiting security vulnerabilities is often non-deterministic. There might be thousands of errors or process crashes before the exploit is successful, and if at least some of those get reported to your telemetry servers it becomes a goldmine for discovering zero-days which are actively being exploited. Microsoft has people who hunt for evidence of zero-days in their telemetry, for example.
