FLOSS is the right way to do IT for everyone. Governments may feel FLOSS is unnecessary/different/unusual at their peril. Sooner or later“Indian government software applications are set to make the shift to open source, potentially boosting the pace at which such programmes are developed, and leading to millions of dollars in savings by moving away from proprietary systems.” the cost and complexity of diverse non-Free softwares will bite them, whether it is at budget-time or upgrade-time or just lack of flexibility as their system evolves and their jurisdiction grows.
In India, the governments have had a lot of serious high-priority problems but now that the old regimes, the wars of independence/separation/clash of cultures are receding consideration of the way forward is first and foremost. A very high priority is to modernize and to adopt IT widely in government. India is a huge country with many regions, languages, and cultures. It needs governments with all the necessary IT to make the country manageable. At the same time, many people and regions in India are impoverished and lacking education. Enter FLOSS. With FLOSS, India can afford many more client computers and servers for the same effort/expense. With FLOSS, India can implement one system in IT and replicate it a thousand times all across the country for little more than the cost of the hardware. That allows India to do more with IT and change IT more rapidly.
The present central government and many state governments have adopted GNU/Linux and FLOSS applications widely and while spending $billions annually on IT can get a lot more IT per $billion. Every customized application that is FLOSS in one government can be adapted by every other government and region for zero licensing cost. Further, FLOSS allows the major amount of tweaking that is required to support all the languages and cultures of the country. Non-Free software just doesn’t work for India any more than it works for other countries who may feel that throwing more money at non-Free software is the answer to any problem.
