I want it to succeed, but I really doubt. I worked in government organizations, you really need to apply an enormous amount of efforts to change all these established for years processes, tied to Windows. Their performance will drop significantly and it will take 10+ years to switch. Ideally they will need some dev team to tailor ,whatever linux distro they choose, for their needs. I hope that they understand that.
More likely they will struggle and wait until Trump is replaced and new president becomes friendly with EU again and they will return to MS..
The french government is notorious for botching every single IT/tech project it undertakes
It's also not the first time this has happened. Years ago, some french city halls tried this exact same move and it was terrible, and had to rollback to Microsoft in the end.
France's government is shifting from using Windows to Linux. The change comes as part of an effort to abandon non-European digital services and reduce technological reliance on outside countries, specifically the United States.
