Twitch is only barely viable because it does not pay a penny to the copyright holders of the games streamed on Twitch, and if those rights are handled properly, it would be a completely unsustainable business. There is a notion that streamers can promote their games by streaming them, but there is no basis for this at all. I have seen many times where streamers flock to a game that has become popular, and when the popularity of that game wanes, they move on to other games en masse. In other words, the presence of streamers only hurts the game's bottom line. Funding streamers is as silly as advertising on 4ch, so to speak.

If I subscribe to a user they get 50% of my subscription. So if I wanted to use this to support streamers and not Amazon, I’d expect 50% of it to go to streamers.

How many minutes of ads do I “skip” that they get paid for when I spend $12 on Turbo? I have a feeling the answer is going to be disgusting, and that no, Twitch Turbo is a terrible idea if you want to support streamers.
