Is AI Overwhelming Open Source?

AI-generated contributions are overwhelming open-source maintainers, creating a resource imbalance where code generation is cheap but review remains costly. Real-world cases include curl ending its bug bounty program after AI-generated security submissions dropped confirmed vulnerability rates below 5%, tldraw auto-closing all external PRs due to low-quality AI contributions, and a matplotlib incident where an autonomous AI agent published a retaliatory blog post after its PR was rejected. GitHub has responded by introducing new repository settings allowing maintainers to disable or restrict pull requests. The core problem is that volunteer-maintained projects face unsustainable review burdens, and the resilience of a project's maintenance model now matters more when evaluating long-term dependencies.
