Austria's Federal Ministry for Economy, Energy and Tourism now has 1,200 employees on the European open-source collaboration platform Nextcloud, leading several other Austrian ministries to also implement Nextcloud. (The Ministry's CISO tells the Register "We can see our input in Nextcloud releases. That is a feeling we never had with Microsoft.") France's Ministry of Economics and Finance recently completed NUBO (which the Register describes as "an OpenStack-based private cloud initiative designed to handle sensitive data and services.") In November the International Criminal Court in The Hague announced it was replacing its Microsoft office software with a European alternative.
