> Stallman was right.

Stallman did not find an economic model that works within our business/legal environment.

Non sequitor. He was right about what companies would do if allowed, and that's the most important thing to keep in mind.

There wasn't much foresight required on his part because companies were already doing things like this way back when. As a trivial example, patents on DRM predate the oft-cited "Right To Read" by a decade or more. Stallman just observed these trends and took an opposing stance without (to GP's point) really addressing the economic incentives and nuances involved.

Maybe his biggest contribution is that his extreme stance and ensuing visibility probably helped shift the Overton window.

Current big tech is based on Stallman-inspired people using their free time to make software. But they are putting MIT lisence because ”someone” had convinced them that GPL is not really free and not socially acceptable!
