Eden: NHS goes to war against open source

The UK's NHS is reportedly closing most of its open-source repositories in response to increasingly sophisticated LLM-based security scanning tools like Anthropic's Mythos. The decision contradicts the UK's Tech Code of Practice and commentary suggests most NHS repos contain low-security-risk content (data, tools, guidance, design). The move highlights institutional concerns about AI-powered vulnerability discovery despite a historical track record of safe open-source.
