Python stands firm: Rejects $1.5M grant from U.S. government over ethical concerns

The Python Software Foundation Rejects $1.5M Grant Due to Ethical Concerns

The Python Software Foundation (PSF) made a significant decision to withdraw its $1.5 million grant proposal from the U.S. National Science Foundation (NSF) citing concerns over potential ethical compromises. The grant was part of NSF’s Safety, Security, and Privacy of Open Source Ecosystems program, aimed at enhancing the resilience and trustworthiness of open-source software infrastructure.

PSF, a non-profit organization dedicated to the Python programming language, initially submitted the proposal in January 2025 with the goal of addressing security vulnerabilities within Python and the Python Package Index (PyPI). The funding was intended to support the development of automated malware-detection tools for PyPI package uploads, which have been posing risks to the platform for some time.

Despite the importance of the grant for enhancing security measures, the NSF’s approval came with restrictive clauses that conflicted with PSF’s core values. One such clause required recipients to refrain from operating programs that promote diversity, equity, and inclusion (DEI). Given that DEI is central to PSF’s mission, the organization found the terms incompatible with its values.

As a result, PSF’s board members unanimously decided to reject the funding, leading to the withdrawal of their grant application. This decision aligns with a similar stance taken by The Carpentries in June 2025, facing DEI-related restrictions under the “Pathways to Enable Open-Source Ecosystems” (POSE) funding program.

In a statement, PSF emphasized the critical need for financial support, urging individuals to join as members, donate, and sponsor the foundation. Despite the setback, PSF remains committed to promoting, protecting, and advancing the Python programming language while fostering a diverse and international community of Python programmers.

Impact on Open-Source Ecosystems

The rejection of the grant sheds light on the growing importance of upholding values such as diversity, equity, and inclusion in the tech industry. The incident serves as a reminder of the ethical considerations that organizations must weigh when seeking funding opportunities.

Call to Action

As the demand for cybersecurity measures continues to rise, it is crucial for organizations like PSF to receive adequate support. By becoming a PSF member, donating, or sponsoring the foundation, individuals can contribute to the advancement of the Python programming language and the broader open-source community.
