If Twitch has troubles to be profitable, why not make a subscription to let Streamers make content in high quality (like 1080p 60fps 6000kbps~8000kbps or more) or Viewers watch high quality streams ?

And the free limit would stays around like 720p 60fps or 1080 30fps with 4000~5000kbps, for example.

On mobile in particular, I think its worth due to the screen size, the diff will not be that annoying, and in bonus it will be less energivorous.

In hope to see less "features" that beg money depending on the generosity of people, more revenues for streamers or even less ads that deteriorates user experience.
