What Software Freedom Conservancy does

Software Freedom Conservancy (SFC) is a 501(c)(3) nonprofit charitable organization founded in 2005 and headquartered in Brooklyn, New York. Its mission is to ensure the right to repair, improve, and reinstall software by promoting and defending free and open source software (FOSS), driving initiatives that make technology more inclusive, and advancing policy strategies that defend copyleft. SFC serves as a fiscal sponsor and nonprofit home for over 40 member projects — including U-Boot, Inkscape, Liblouis, and OpenWrt — providing infrastructure services such as Git repository hosting (Forgejo and Kallithea), mailing list management (Mailman), Etherpad collaborative editing, wiki hosting, IRC channel management, and Forgejo-based code hosting, alongside legal assistance, governance frameworks, and fundraising support.

SFC's core offerings sit at the intersection of legal, technical, and advocacy work. The Copyleft Compliance Program investigates and enforces GPL, LGPL, and AGPLv3 violations; Impact Litigation defends software-user rights in court — most prominently the ongoing Vizio Smart TV GPL case filed in October 2021 and the May 2026 Bambu Lab AGPLv3 enforcement, which produced the baltobu reverse-engineering initiative and a $250,007 right-to-repair fundraiser. Supporting products include Use The Source (a tool for evaluating GPL-licensed source code candidates), OpenWrt One (the first wireless router designed for software freedom and right to repair), the annual FOSSY conference (2025 in Portland, 2026 in Vancouver), the Outreachy and ICR internship programs (over 1,000 paid internships facilitated), and the Give Up GitHub advocacy initiative. SFC also publishes policy outputs including LLM-backed Generative AI Recommendations for FOSS Contributions and The Corresponding Source podcast.

The business model is donation-driven: SFC generates revenue entirely through individual donations, sustainer memberships at $128/$256/$512/$1,024 giving levels, periodic annual fundraisers with match challenges, occasional corporate sponsorships, and grants. No products or services are sold. Fundraising signals indicate a 2024 end-of-year raise exceeding $475,000 and growing match challenges ($211,927 in 2025; $251,939 in the 2025-2026 cycle). The organization is governed by a Board of Directors and operates with a staff of 11–50 led by Executive Director Karen Sandler, Policy Fellow Bradley M. Kühn, Director of Compliance Denver Gingerich, Operations Manager Tracy Homer, and Community Organizer Daniel Takamori, with no parent, subsidiaries, or institutional investors.

Partnerships

Eleven partnerships are on record, tiered core and minor.

• FULU FoundationcoreTechnology or IntegrationFULU Foundation publicly supported independent developer Paweł Jarczak by offering to host his OrcaSlicer-BambuLab fork, which restored cloud connectivity to Bambu Lab printers using AGPLv3-licensed code. SFC coordinated with FULU as part of its comprehensive response to Bambu Lab's AGPLv3 violations.
• OutreachycoreStrategic or Co-development PartnerSFC actively participates in and supports the Outreachy internship program, which provides paid internships in free software for individuals who face under-representation, systemic bias, or discrimination in tech. SFC and ICR combined have facilitated over 1,000 paid internships.
• ICR (Initiative for Cryptographic Software?)coreStrategic or Co-development PartnerSFC supports ICR (Initiative for Cryptographic Research) alongside Outreachy, together having provided over 1,000 paid internships in free software and scientific research with FOSS.
• IEEE VancouverminorStrategic or Co-development PartnerIEEE Vancouver partnered with SFC to co-organize FOSSY 2026 (Free and Open Source Software Yearly conference), bringing organizational support and faculty/staff/student involvement from the University of British Columbia.
• University of British ColumbiaminorStrategic or Co-development PartnerUBC faculty, staff, and students are supporting FOSSY 2026 as a venue host and community partner for the conference taking place August 6-9, 2026 in Vancouver, BC, Canada.
• Nextcloud and IONOSminorStrategic or Co-development PartnerNextcloud partnered with IONOS to fork OnlyOffice's code to create Euro-Office, a sovereign office suite for EU institutions, after OnlyOffice attempted to enforce contested license terms. SFC's policy fellow Bradley Kühn authored an analysis supporting the fork as valid under AGPLv3§7¶4, validating their approach.
• Free Software Foundation (FSF)coreStrategic or Co-development PartnerFSF provided a declaration in support of SFC's motion in the Vizio case, confirming that GPLv2 was intended to grant third-party beneficiary rights. SFC and FSF share the mission of advancing software freedom and copyleft licensing.
• Texas InstrumentsminorStrategic or Co-development PartnerTexas Instruments, a sponsor of the U-Boot project, expressed strong support for U-Boot joining SFC, recognizing the critical importance of community infrastructure that enables the open source bootloader used across TI embedded processors.
• Linaro LimitedminorStrategic or Co-development PartnerNeil Armstrong, Senior Software Engineer at Linaro Limited, joined the U-Boot Project Leadership Committee and expressed support for U-Boot joining SFC to ensure a successful future under the conservancy's umbrella.
• Keep Android Open CoalitionminorStrategic or Co-development PartnerSFC signed an open letter to Google alongside many other organizations, asking Android to continue allowing users to install what they want on their phones and opposing new developer registration requirements that restrict sideloading.
• Free Software Foundation Europe (FSFE)minorStrategic or Co-development PartnerSFC referred the European Commission to FSFE's comments in its submission on European Digital Ecosystems, collaborating on policy advocacy to avoid duplicating points already well-made by FSFE.

Recent moves6 records

Expansion highlights6 records

Direct peers

• Free Software Foundation: The original free software advocacy nonprofit founded by Richard Stallman; shares SFC's copyleft/license-purity mission and is closely allied (FSF filed a declaration supporting SFC's Vizio motion). SFC is often framed as the enforcement/legal arm of the broader free software movement that FSF anchors.
• Software in the Public Interest (SPI): A 501(c)(3) nonprofit fiscal sponsor for FOSS projects (e.g., Debian, PostgreSQL, LibreOffice). Directly comparable to SFC's member-project hosting and fiscal-sponsorship model, making it the closest functional analog.
• Apache Software Foundation: Foundational nonprofit providing legal, financial, and infrastructure support to open source projects under the Apache License. Comparable in structure, scale, and role as a project umbrella, though more permissive-license oriented than SFC.
• Eclipse Foundation: Nonprofit foundation supporting open source projects with governance, IP, and infrastructure services. Directly comparable peer in providing legal home and operational support to FOSS communities.
• Open Source Initiative (OSI): 501(c)(3) nonprofit that defines 'Open Source' via the OSI Approved License list and advocates for open source in policy. A direct advocacy peer, though OSI focuses on standards/definitions rather than enforcement.
• OpenSSL Software Foundation: Nonprofit stewarding a single flagship FOSS project (OpenSSL). More narrowly focused than SFC but comparable in providing a nonprofit legal/institutional home for a critical open source codebase.

Broad incumbents

• Linux Foundation: The largest open source industry foundation, hosting projects such as Linux, Kubernetes, and PyTorch. Acts as a comparable broad incumbent in the FOSS fiscal-sponsorship space, though its corporate-neutrality model differs from SFC's advocacy posture.
• Electronic Frontier Foundation (EFF): Major digital rights nonprofit litigating and advocating on privacy, free speech, and innovation — adjacent to SFC's software-freedom mandate. Comparable as a digital rights litigator/advocate with donation-driven funding.
• Mozilla Foundation: Nonprofit arm of Mozilla focused on healthier internet, supporting FOSS-adjacent advocacy and grants. Comparable as a values-driven, donation-funded nonprofit advocating on internet/software issues at policy levels.

Regional players

• Free Software Foundation Europe (FSFE): European counterpart to the FSF; collaborates with SFC on EU policy submissions (e.g., European Digital Ecosystems). Directly comparable advocacy mission but with a regional, Europe-focused scope.
