Digital sovereignty isn’t about buying European software - it’s about control and choice.
Open source and open standards give governments the ability to operate independently, avoid vendor lock-in, and switch providers when needed. That’s real sovereignty.
Open Source helps but it’s also important to fix the incentive structure and startup environment such that products are fully competitive. Doubt that merely throwing money at it (in the form of grants at least, which is what usually govs do) fixes the issue.
