honestly, initially i thought it was a rogue employee at bsnl who was doing it. but people have filed RTIs and it is pretty much confirmed that they are doing it by choice. they do not see this as something wrong. they have indicated in the past that customers can opt-out by filing a request. but overall, it is a shitty thing they are doing. and it seems to be purely focused on generating revenues at the cost of their paying customers. http traffic is of very little value to them anyways because the number of http domains one would be visiting these days is pretty small.
