There are many genuinely talented and accomplished computer scientists from and in India; however, if you are an internet personality and you are constantly bombarded with blatant requests, or even demands, which are indeed poorly written and come off as just trying to get something from you, it points to a possible culture difference. A lot of these requests come from students who are looking for shortcuts, or think that because you have code on GitHub, they are entitled to your personal support. India is a huge country, so even if a very small part of the population acts this way, it can be overwhelming and form some strong opinions on the receiving end - and this is not limited to India.
