I can't tell what "Person" in the headline maps to. Like, for a non-tech company, is that every employee, every employee in the IT org, or every developer in the IT org?
IC engineer. That's the brightest line for comparison across companies (dim though it may be), as well as the primary role whose productivity is materially multiplied due to open source (i.e., imagine if the engineer had to build everything they get from open source).
