Native Korean here, It's way worse here. It has been a decade since former telecom board members in the chief of Korea Communications Commission, which should prevent this in the first place.

The Netflix trial back in 2021 beforehand was due to SK Broadband (South Korean ISP) having lots of NTT bound traffic since they didn't join the Netflix's OpenConnect Program while requesting Netflix to co-locate in their server main content servers in (the SK Broadband). The results? Netflix found guilty for causing those traffics.

For your information, You can't establish an ISP in South Korea since the law forbids anyone other than "3 major telecom"s (SK Broadband, KT, LG U+). Regulations protecting telecoms and making sure CPs getting properly ripped off (Bonus point if you are not domestic business).

Are bandwidth fees just as high for any domestic Korean company creates a Twitch competitor?

Or do the 3 major telecoms operate their own streaming services, so only companies under their umbrella can afford a site like Twitch?

Yes, it is the same price. The biggest Korean streaming service, AfreecaTV, pays 1/3 of the total revenue.

So major real-time streaming services in Korea relies on peer-to-peer streaming to reduce the cost.

How effective peer-to-peer there? Is CGNAT widely deployed? Is IPv6 available to most people?

[kbumsik]

They were able to reduce the network price from $70m/yr to $12m/yr [1] (their revenue was around $220m/yr btw).

There is almost no IPv6 yet since we still have enough IPv4 addresses. I am not sure how it is implemented but p2p has been often used in Korean services since 20 years ago.
