How the telecoms market is irrelevant to this discussion. Of course they're going to market having access to the most popular websites and apps. Hell, they probably use the same advertising when selling real internet service.
2. Also irrelevant. Internet in train stations is not comparable at any level to cellular data connectivity for 10's of millions of people.
3. You are right in this point, but I also find it presumptuous that the Indians with enough money to have internet are the ones dictating what is good for the Indian people without enough money for internet.
