OSI 2026 State of Open Source Report: vendor lock-in fears surge 68% YoY, maintenance burden grows

The Open Source Initiative's 2026 State of Open Source Report, based on 700+ responses and produced by Perforce OpenLogic with OSI and Eclipse Foundation, found that 55% of organizations cite avoiding vendor lock-in as their primary driver of OSS adoption — up 68% year-over-year. In the EU/UK, 63% cite vendor lock-in versus 51% in North America, reflecting digital sovereignty concerns. 60% of large enterprise (5,000+ employees) engineers spend 50%+ time on maintenance versus innovation. 31% of enterprise Java teams devote only 10-25% of time to new features. Organizations with end-of-life software (Tomcat, Spring Boot) had 2x compliance audit failure rates. The report quantifies a strategic shift from cost-saving to digital sovereignty as the primary OSS adoption driver.
