The Tech Giants and Giant Slayers report (April 2026) argues that the UK’s over-reliance on foreign tech companies is an urgent national security risk. It calls for a strategic shift toward “Digital Sovereignty” through Open Source technology and the “Digital Commons,” which could save the government millions and boost the UK tech economy by billions.
A landmark report released on April 14, 2026, by the Open Rights Group (with forewords from cross-party MPs including Clive Lewis and Siân Berry), issues a stark warning: the UK is in the midst of a “crisis of digital dependency.”
The report, titled Tech Giants and Giant Slayers, argues that the UK’s reliance on a handful of foreign tech giants—primarily from the US and China—poses an urgent threat to national security, economic stability, and democracy.
The problem: A crisis of dependency
The UK currently relies on foreign proprietary technology for its most critical infrastructure, from government databases to cloud computing.
This creates four primary “Chronic Risks”:
Economic extraction:
A small number of “strategic suppliers” dominate the market, leading to vendor lock-in. The Competition and Markets Authority (CMA) estimates the UK is overcharged by at least £500 million a year in the cloud market alone.
Security vulnerabilities:
Dependency on foreign code makes the UK vulnerable to service withdrawals, sanctions, or even cyber-attacks.
Surveillance and legal conflict:
Under laws like the US CLOUD Act or China’s National Intelligence Laws, foreign governments can compel tech companies to hand over UK data, bypassing British legal protections.
Democratic distortion:
Big Tech’s lobbying power shapes UK policy, while its algorithms increasingly mediate how citizens interpret political events, effectively “shaping public debate itself.”
The solution: The Digital Commons
The report argues that the only way to “slay the giants” is to shift toward the Digital Commons—a shared ecosystem of Open Source software, open standards, and open hardware.
Contrary to the idea that Open Source is just a “hobbyist” endeavour, the report provides massive economic evidence for its value:
Economic impact:
National economies would be 2–3% smaller without Open Source.
Widespread use:
Open Source makes up roughly 70% of the codebase in 95% of all proprietary systems.
Return on investment:
EU research suggests every £1 invested in Open Source returns £4 in economic value.
The “Public Code” Rule:
The report champions the “Public Code for Public Money” policy—if taxpayers pay for software development, the resulting code should be open for all to use and improve.
A roadmap to sovereignty
To reclaim control, the report offers several key recommendations for the UK Government:
Reset digital policy:
Move away from “passive procurement” and make Digital Sovereignty a central national security goal.
Follow the European lead:
Adopt strategies similar to Germany, France, and the Netherlands, who are already investing in sovereign open-tech alternatives.
Build In-House Expertise: Rebuild technical leadership within the Civil Service to reduce reliance on expensive external consultants.
Empower Regulators: Give the CMA and other bodies the teeth to enforce interoperability, allowing smaller UK “Giant Slayers” to compete with Big Tech.
