No. When one is presented numbers : when some one shows you comparison
Look for what's not there : look what data is missing.
In this case hotstar's billion minutes of watch time : voot has compared about watch time of its against Sony liv and zee5 but not with hotstar.
I don't see anywhere him telling voot data is fake. He is telling show the full data of watch time he hasn't talked about MAU.
And also voot has never said it's no.1 in watch time
