I don't see how it is unreasonable to expect immigrants to adapt themselves to the country they voluntarily choose to enter.
I'm contemplating a move to Pune - if I go, I certainly wouldn't expect the Indian taxpayer to pay for me to learn Hindi. Adopting yourself to the local culture/conventions/language/etc is your job - if you can't handle it, stay home.
I wouldn't expect them to pay for you to learn Hindi either. However, Marathi might get you further in Pune, especially with the locals, as it's the official language of the region.
