Linux

Based.

For governments, I think the priority should be exchange and archive formats. Regardless of what apps and platforms they use, I as a citizen should be able to read that data via free software. Govt should be able to read what I provide to them. Govt in the future should be able to access archives if they have moved to free software.

Next is the platform ( the OS and the web browser ). You can run your proprietary video editing on Linux. If demand on the scale of ALL European gov moved to Linux, I assure you that Linux versions of the software they need would exist ( even if still proprietary ). I use Outlook on Linux every day. I also use Teams ( usually on Edge ). RMS would hate me. But I only archive to AV1 and Opus, never HEVC and AAC. Most of what I use is FOSS.

Least important really is the apps. I have no problem with companies solving problems better than FOSS and getting paid for it. Even by gov. As above though, those that do not need the “better” version should be free to use something else. And the “default” ( for things like basic docs ) should be FOSS too. This is just not as important as the file formats and platforms.

I feel like they don't know the magnitude of that what means.

Very cool but unlikely to work
