I don't think Microsoft Office is any better than LibreOffice for general users. Most of the Indian government officials are tad computer illiterate. They would not know what they use.
I recently attempted to move everyone in my office to libreoffice where possible and was met with a very large resistence from people who's spreadsheets simply did not work.
it's hard telling people that they have to edit functions/macros that were set up by someone smarter than them 10 years ago.
A UI can be thought of being easy-to-use with the frequency of usage. I have been using Linux for many years. Now, whenever I use Windows the only thought in my mind is how can someone use a software so clumsy.
