This article[1] highlights the ridiculously regressive arguments given by the Indian ISPs against net neutrality, as reflected from the TRAI’s consultation paper:

  1. OTTs negatively affect our revenue
  2. OTT apps use very less data
  3. OTTs earn too much
  4. Net neutrality is already dead
  5. Compression algorithms further reduce our profits
  6. Too much freedom of expression is bad

Here's how the telecom regulatory authority of India defines OTT:

"The term over-the-top (OTT) refers to applications and services which are accessible over the internet and ride on operators’ networks offering internet access services e.g. social networks, search engines, amateur video aggregation sites etc. The best known examples of OTT are Skype, Viber, WhatsApp, Chat On, Snapchat, Instagram, Kik, Google Talk, Hike, Line, WeChat, Tango, e-commerce sites (Amazon, Flipkart etc.),Ola, Facebook messenger, Black Berry Messenger, iMessage, online video games and movies (Netflix, Pandora)."
