Twitch has currently END its business in Korea, Twitch does not have to pay network usage fees in Korea.
Korean viewers (or viewers who visit Korea and use Twitch) were uncomfortable with the measures taken by Twitch Korea to reduce network usage fees (limiting broadcasts to 720P, disabling clips and replays).

I hope Twitch puts an end to these measures because now they don't have to pay Korean carriers.

Additionally, there are still many broadcasts outside of South Korea on Twitch, and there are still Korean users who want to enjoy them in NORMAL quality.
