Adoption of free and open-source software by public institutions
The use of free software instead of proprietary software can give institutions better control over information technology. A growing number of public institutions have started a transition to free-software solutions. This grants independence and can also address the often-argued need for public access to publicly funded developments. This is the only way that public services can ensure that citizen data is handled in a trustworthy manner since non-free software doesn't allow total control over the employed functions of the needed programs.

In August 2016, the United States government announced a new federal source-code policy. This policy mandates that at least 20% of custom source code developed by or for any agency of the federal government must be released as open-source software. In addition, the policy requires that all source code be shared between agencies. The public release is under a three-year pilot program and agencies are obliged to collect data on this pilot to gauge its performance. The overall policy aims to reduce duplication, avoid vendor 'lock-in', and stimulate collaborative development. A new website provides "an online collection of tools, best practices, and schemas to help agencies implement this policy", the policy announcement stated. It also provides the "primary discoverability portal for custom-developed software intended both for Government-wide reuse and for release as OSS". As yet unspecified OSS licenses will be added to the code. The US Chief Information Officer Tony Scott, co-author of the policy, blogged "This is, after all, the People's code. Explore it. Learn from it. Improve it. Use it to propel America's next breakthrough in innovation."
