I know someone that works in the central government of an EU country and have persuaded her to talk to the IT department in the ministry where she works to try to move away from Microsoft products. The short answer: "It's not possible for us to move away from Microsoft". And it's not that they don't want to, but they have extremely low IT resources + the employees are very reluctant to make any change. Sometimes they introduce a new program, or update an older one and there's massive whining in the entire ministry. These public employees should really try to adapt more and understand that digital environments have become crucial for independence, privacy and self-reliance.
