We can also say that Airtel and other telecom were looting Indian customers before Jio came up.
Just because Jio is offering competition doesn't mean they are corrupt.
Hahaha, one look at the world's telecom ARPUs should give you a better clue about whether you can say that Airtel was 'looting Indian customers' or not. Also I never said that Jio is corrupt because it's cheaper. Just try to read about the changes in the telco regulation as Jio launched and what industry people have to say and the answer will be clear.
