Which is weird, because out of all of the platforms, Twitch keeps the biggest cut of ad revenue. They rate all ads at a fixed cost regardless the size of the streamer (which is bonkers). Twitch should have systems in place by now to make the most off an ad run on the biggest streamers, but they're doing a really poor job of it. Amazon does seem to be exerting some influence here to rectify this though (see recent metrics changes to Twitch APIs).
This actually leads me to believe that Twitch users are probably at like a 95%+ AdBlock install rate.
