People in India are deeply influenced by fake narratives and propaganda on Whatsapp & social media.
With the technological advancement & competition, products & services tends to become cheap....Before Jio, Tata Teleservices disrupted the market with per sec billing and tariff was reduced drastically but they didn't promise lifetime free & killed competition.
In 1998, i bought assembled PC for around 40k which was huge amount and in 2005, compaq presario desktop for around 45k...Today a laptop with much better configuration can be bought for 30k.
In 2011, i bought 42 inch LCD for 45k and today a 42 inch LED is available at almost 1/3rd rate.
If competition would not have been killed then data would have been much cheaper than it is today.
Jio's launch was not to provide cheap data but it was part of bigger plan to directly reach the masses through whatsapp university/social media and bypass the traditional media which was neutral at that time.
