But it wasn’t until the free software movement shed its rebellious roots and rebranded as the more business-friendly “open-source movement” that it really took off. One of the most crucial figures in this effort was Tim O’Reilly, founder and CEO of O’Reilly Media, who built his business empire by identifying the pieces of the free software movement that could be commodified. Suddenly, corporations that had previously considered open source to be dangerously redolent of “communism” were starting to see its value, both as a way of building software and as a recruitment tactic. From there, an entire ecosystem of virtue-signaling opportunities sprang up around the marriage of convenience between the corporate world and open source: conference and hackathon sponsorships, “summers of code,” libraries released under open licenses but funded by for-profit corporations.

If that counts as a victory, however, it was a pyrrhic one. In the process of gaining mainstream popularity, the social movement of “free software”—which rejected the very idea of treating software as intellectual property—morphed into the more palatable notion of “open source” as a development methodology, in which free and proprietary software could happily co-exist. The corporations that latched onto the movement discovered a useful technique for developing software, but jettisoned the critique of property rights that formed its ideological foundation.
