He claimed that ACT contributes by 30% - that's pretty much correct. Also note that Steam detects ACT and Beam Cable as different networks.
BSNL does have the highest subscriber count. But the question is does it generate the highest network traffic in India?
That's the issue isn't it? There are no specifics.
Let's say these are the consumption:
X-500TB
Y-200TB
Z-150TB
W-120TB
Rest-30TB
Here Z comes third while contributing only 15% while Y comes second by contributing 20%, X comes first by contributing 50%. Since the steam chart is sorted according to data consumption, BSNL has the second highest contribution, period. It can be 50%, it can be 10% but it will be higher than all the items below it. But yes, if you consider Beam and ACT together they can overthrow BSNL, take my example. here Z+W is higher than Y. So, that chart is inconclusive. Its not correct to claim by comparing speed alone as the data consumption as well as subscriber count are not mentioned.
Provided ACT only provides data in a few cities and BSNL provides throughout India, I assume that BSNL consumes the highest data.

There is something very wrong with the Indian internet industry.
Take for example my local provider Wishnet. They purchase bandwidth from Airtel and offer 1mbps true UL for ~850/- incl of all taxes. They also provide 6mbps night ul from 1:00AM to 9:00AM, and stuff like caching and local peering. Yet somehow they make profit. Not only that they recently decreased the cost of most of their plans by ~30%, so how are they pulling it off while Airtel provides $hit wired plans in Kolkata?

Not just wishnet, all local providers in Kolkata buy traffic from Airtel or Reliance and they make profit. How are they doing it?
Question I'd also like and answer is from whom does ACT purchases bandwidths? They don't own cables or have any stake in the NIB I or II. They are bandwidth reseller. Who do they buy their traffic from?
