Have a chat to someone who works for an ISP or try some research ( a response you so often give) regarding ISP traffic data during say the RWC or Rugby Championship as examples.
As advertising is a "Freeview offering I don't see how the reply regarding the cost of advertising is nonsensical.
I don't see how people streaming rugby equates to wanting Sky for free, which I think was your point. Maybe they just want to watch Rugby, which ought to be available FTA since it is a national sport. One of Sky's marketing tactics has been to cut off public access to important content by encasing it in exclusive rights deals to force viewers to subscribe to Sky. As things like this move to alternative platforms, I doubt there will be many wanting Sky for free or any other way. FTA is not getting it for free, by the way, since you pay for it by enduring the commercials.
Speaking of which, your second point is nonsensical because the cost of buying advertising has nothing to do with watching television. You are trying to make a connection that doesn't exist.
