EU "digital sovereignty" will not save EU citizens from venture capitalists, big tech oligarchs, surveillance capitalism, for-profits inevitable enshittification, nor fascism or authoritarianism. The only thing that will is open source.
The goal should be for all governments to switch to 100% open source hardware and software. Only pay for services and support that provides and directly contributes back to open source. That way public money goes to public code โ the public good โ governments can pool resources and achieve economies of scale that supersede big tech, and every other economy โ including the poorest โ would benefit.
The only reason Linux is "behind" is because governments have collectively spent hundreds of billions of dollars on for-profit, proprietary software and hardware vendors.
It wound likely be more expensive in the short term, but would be significantly cheaper long term, and enable national security and digital sovereignty benefits that are literally impossible with proprietary tech.
