The Open-Source Kingdom
For years, HashiCorp was a poster child for successfully monetizing open-source software. The company’s flagship product, Terraform, became the undisputed king of “Infrastructure as Code,” allowing developers to define and manage their cloud computing
resources with simple, elegant code. Its tools were powerful, beloved, and—crucially—free to use under a permissive open-source license. This strategy built a massive, loyal community of developers who contributed to the code, evangelized the product, and fueled its widespread adoption. HashiCorp's identity was inextricably linked to the open-source ethos; they weren't just using the model, they were defining it for a generation of infrastructure tools.
The Billion-Dollar Freeloader Problem
But a problem was brewing, one common to open-source pioneers. Other large companies, including direct competitors and massive cloud providers, were taking HashiCorp's free, open-source code and building their own competing commercial products on top of it. They were profiting from HashiCorp's years of investment without contributing back to the project. This practice, sometimes called “strip-mining,” put HashiCorp in a strategic bind. As a public company facing pressure to grow and become profitable, it couldn't afford to keep giving away its most valuable asset to its rivals. The very openness that made them popular was now threatening their long-term survival.
Drawing a Line in the Sand
On August 10, 2023, HashiCorp made its move. The company announced it was switching the license for Terraform and its other core products from the open-source MPL 2.0 to the more restrictive Business Source License (BSL). In simple terms, the BSL meant the code was still publicly available, but direct competitors could no longer use it to build commercial offerings that rivaled HashiCorp's own paid services, like Terraform Cloud. For the vast majority of users—companies managing their own infrastructure—nothing would change. But for the companies profiting from their work, the free ride was over. It was a pivot HashiCorp had long resisted, a clear departure from its founding principles.
The Community Strikes Back
The backlash from the open-source community was immediate and fierce. Many felt betrayed, arguing that HashiCorp was pulling up the ladder after climbing to success on the back of a community it was now abandoning. The move was seen as a rejection of the open-source philosophy. This anger quickly coalesced into action. A coalition of competitors and community members, feeling the license change was a “poison pill” for the ecosystem, created a fork of Terraform's last open-source version. This fork, named OpenTofu, was placed under the stewardship of the Linux Foundation, guaranteeing it would remain truly open source forever. Suddenly, HashiCorp had a credible, community-backed competitor built from its own code.
A Necessary Betrayal?
Years later, the dust has settled into a new reality. HashiCorp, which was acquired by IBM in 2025, continues to develop Terraform under the BSL, focusing on integration and enterprise features. OpenTofu has established itself as a viable, drop-in replacement, with a community of its own driving new features. The pivot, while painful, was likely a calculated business necessity driven by financial pressures and the realities of competing in a cutthroat market. HashiCorp traded a portion of its community goodwill for commercial defensibility. Whether it was the “right” choice remains a debate, but it fundamentally altered the landscape, forcing a maturity in the market and proving that even the most deeply held principles can bend under billion-dollar pressures.
