Indians use English for their own purposes. It is a common language of government, academia and the corporate world because it bridges the various differing native languages within India such that someone from Punjab can communicate with someone from Tamil Nadu. The unfortunate flipside of this is that it remains very class-bound, with poorer Indians have little access to English and are thus cut off from the discourse of the upper classes. Nonetheless, such writers are not writing for you or me, we are just fortunate enough to be able to listen in.
Nor do Indians care what some Canadian thinks about how they should use language. Indeed, as the second largest English-speaking nation in the world it is as much their language as ours. This is the flip-side of English as a "global language" -- it is no longer ours to control. Get used to it.
India has already left its mark on the English language with words like "bungalow", "juggernaut", and "thug". I have no doubt that a century from now India's influence on the global language will have multiplied tenfold -- certainly far exceeding any Canadian influence -- and many of the "foreign" (i.e. Hindi, etc.) words that you do not understand will be understood by many non-native speakers.
