"The venture capitalist and Facebook board member Marc Andreessen"
That pretty much sums up what is going on here, Mr Andreessen, for all his fine words and logical fallacies is really only interested in the bottom line. He and Zuck have seen a lucrative market which is just ripe for the
fplucking with lots of customers who they want to get hooked on their product with a "free sample" knowing that if they can get in first, they'll have an almost guaranteed monopoly which they can exploit and sell to their advertisers.
This has *nothing* to do with benefitting the Indian people, nor is it that "Western activists" are "seeking to prohibit any free data services, which they consider fails their politically-correct definition of ‘net neutrality’", that's a total red herring, it is people who can see the risks of letting them control it and want to prevent that from happening.
It also has nothing to do with colonialism or nannying or thinking the Indian people are too stupid to understand, it's about making sure that the politicians and regulators don't decide (based on generous "campaign contributions" or any other such things) that giving it all to FB would cripple any local attempts to do the same thing since FB could give it away for free for long enough to bankrupt any competition.
Personally I don't think that's a good thing and Indian businesses should be allowed to develop their own products for the benefit of their own people.
