I do not want TRAI to allow my service provider to charge me for using WhatsApp or YouTube or Skype or Viber.

You must have heard of Aaron Swartz, who fought for net neutrality in the USA back in the days but Secret Service gunned him down.

We do realize that the government is funded by all the big companies and most of the big businessmen get around to favour the law to themselves by lobbying with the government. But, its essential to realize the essence behind the fact that Bharti Airtel's CEO said -

'we have created such a massive infrastructure for the country we expect something in return.'

But its important to realize companies as big as his - which not only operate in India but elsewhere worldwide, do have some social responsibility. Some responsibility to the society. These companies should take note they are using up society's resources, and ought to do enough to replenish these resources.
By not charging for something which they do not have jurisdiction on is completely mindless. Their job is to provide internet and they are doing so. They never stated any terms & conditions for which app usage and what site I visit will there be a separate charge.

Not charging for this trash shall be in the future  interests of telcos, as they do not want to lose out on their market.

I DO SUPPORT NET NEUTRALITY.
