@M0YNG Skills are just the tip of the iceberg.

What about RMS's unwavering lifelong commitment to the cause of free software? I don't see anyone else who even comes close.

The contribution of the GPL alone eclipses what most other hackers will achieve in their careers, and constitutes far more than a "handful of things" in itself.

I would contend that Stallman has, across 35 years in the service of free software, enabled and inspired far more people than he has scared off or otherwise demotivated. This cannot be quantified, of course, so I won't argue the point.
