They aren't making money from this, but they are likely operating at a scale where they either don't notice if 1000 nerds on the internet are piggybacking their feeds, or don't care all that much.

It is not likely useful to them in negotiating ad rates, at least not with how advertising is usually bought/sold, because the broadcaster has almost no information (if any) about anyone watching these streams, including if it's even a person. It's possible they could fold it into a more general ad package that places a lot of weight on total view/viewers numbers, but that is a lot less common these days, and when it is done, the rates tend to be much lower

Yea I meant it is an argument they can use but not a good metric at all. I agree that mostly they just do not care. This tool only means that they'll get more international views from curious people but in the end it means nothing.
