Meanwhile, travel portal Cleartrip and media giant Times Group logged out of of Facebook which defended its platform.
At the same time, the Internet and Mobile Association of India (IAMAI) alleged that TRAI was furthering the agenda of telecom operators on this issue.
The telecom sector regulator has invited public comments on a discussion paper for policy framework on net-neutrality and internet-based messaging and calling service providers such as WhatsApp, Skype, Viber and Google Talk.
An intense debate, including on social media platforms, began on the issue of 'net neutrality' after some telecom firms, including Bharti Airtel and RCOM, announced services that are being billed as going against the concept of maintaining equal internet access for all.
These platforms claim to allow users to access a variety of mobile and internet applications for free, but the critics allege that these services restrict the 'free' access to a select group of websites and apps and therefore sabotage the entire concept of keeping the internet free.
Buckling under a growing public outrage, ecommerce giant Flipkart decided to 'walk away' from Airtel Zero, while travel portal Cleartrip also pulled out of '' platform of Facebook, where RCOM is a partner.
