Airtel...launched a service called Airtel Zero...This means if an app pays money to Airtel, consumers on Airtel network will be able to use it without paying any data charges. For example, consumers who have Flipkart installed -- Flipkart is rumoured to be a company paying Airtel money to be part of the Zero plan -- will be able to access the app without paying data charges....What the company doesn't mention is that this service violates the concept of net neutrality, a basic principle around which the internet has been built...It has serious repercussions.
