This is going to BLOW up the twitch gaming community with all the infighting now that everyone knows how much everyone else makes. Wow.
And "premium contracts" to keep talent were offered pretty much since day 1, just looked quite different back then. (Mainly just differentiated in sub share. For the last 2-3 years they also include better ad payouts (and a minimum of ad time), boni for minimum amount of hours streamed, etc.))
And... every streamer who only cares a bit about his business already knows, at least for the most part, what kind of contract other streamers are on.
So don't think there will be any (real) drama - but I also didn't see or hear of any extreme unexpected outliers.
