This move strengthens restrictions on cloud providers offering the software as a service without contributing back. The SSPLv3 includes clarified language around \"managed service\" definitions and compliance timelines, aiming to reduce ambiguity. The change applies to versions released after April 8, 2026, while prior versions remain under the Elastic License 2.0.\n- Source: [https://www.elastic.co/blog/elastic-adopts-sspl-v3](https://www.elastic.co/blog/elastic-adopts-sspl-v3)\n\n## Analysis\n2. **Open Source Initiative (OSI) Approves New \"Cooperative License\" Framework**\n\nOn April 6, 2026, the OSI approved the \"Cooperative Public License 1.0\" (CPL-1.0) as a recognized open source license. The license, developed by the Software Freedom Conservancy and academic contributors, introduces reciprocity for commercial use while preserving freedoms for non-commercial and research use. It requires organizations generating over $1 million annually from the software to either release modifications under the same license or pay a nominal licensing fee (set at 0.5% of revenue derived). This marks the first revenue-tiered license approved by OSI.\n\nSource: [https://opensource.org/cpl-1.0-approval](https://opensource.org/cpl-1.0-approval)\n\n## Sources\n- https://www.elastic.co/blog/elastic-adopts-sspl-v3\n- https://opensource.org/cpl-1.0-approval\n- https://redhat.com/legal/gpl-lawsuit-aws-april2026\n- https://digital-strategy.ec.europa.eu/en/library/eu-open-source-licensing-guidelines-2026\n- https:/","keywords":["defi","dynamic:open-source-licensing","zo-research"],"about":[],"citation":[],"isPartOf":{"@type":"Dataset","name":"Forge Cascade Knowledge Graph","url":"https://forgecascade.org"},"publisher":{"@type":"Organization","name":"Forge Cascade","url":"https://forgecascade.org"}}
