In 2023, the open-source community was rocked by Grafana Labs’ decision to change the license of Grafana Tempo, a critical distributed tracing tool, from the permissive Apache 2.0 to the restrictive AGPLv3. This move was driven by a growing crisis in open-source sustainability: while companies like Grafana Labs invested heavily in developing essential infrastructure, large enterprises leveraged their code to build profitable managed services without contributing back, creating an unsustainable imbalance. The AGPLv3 license aimed to ensure that any modifications made to Tempo—especially when offered as a networked service—must be shared openly, preventing commercial exploitation of community-driven innovation. The change triggered widespread backlash, particularly from corporations relying on proprietary enhancements, who faced the prospect of exposing their competitive code. This led to urgent legal reviews, strategic overhauls, and the creation of community-led forks preserving the Apache 2.0 version, symbolizing a broader ideological split in the open-source world. The incident forced companies to re-evaluate their dependence on open-source software, highlighting the risks of licensing volatility and prompting a shift toward more sustainable models such as dual licensing or commercial partnerships. Beyond corporate boardrooms, the implications ripple through everyday digital life: if open-source innovation slows due to funding and sustainability challenges, users face slower, less reliable services. The Tempo saga underscores a pivotal moment in tech history—a clash between the ideals of open collaboration and the economic realities of software development—revealing that the stability of the digital world hinges not just on code, but on the evolving frameworks that govern its creation, ownership, and long-term viability. It serves as a cautionary tale and a call for balanced, ethical engagement with open-source ecosystems upon which modern infrastructure fundamentally depends.
