That applies the other way around too. That’s called a network effect.

I feel like streamers are harder to get than viewers. Viewers just need to go to the site and watch a streamer, but a streamer needs to set it up to stream.

They could probably get viewers back fairly easy through advertising or tie ins to games, but doing that with streamers would likely be harder.

Streaming from console or gpu driver addon trash is normally as simple as clicking a link and/or logging in to the site.
