An anonymous reader writes with news that 25,000 staff across 13 hospitals in Denmark will be switching to LibreOffice over the course of the next year. "The group of hospitals is phasing out a proprietary alternative, 'for long term strategic reasons,' which at the same time saves the group some 40 million Kroner [about $7.7 million] worth of proprietary licenses. The ditching of the proprietary alternative is a consequence of the group's move to virtual desktops, allowing staff members to log in on any PC or thin client. The group found that deploying this new desktop infrastructure would 'trigger unacceptably high costs' for proprietary office licenses... The move is Europe's second largest migration project involving public administrations using an open source office suite."
