Fans of pop originating in USA, Canada and UK do not really pay too much attention to whatever their faves do there.
A similar attitude was seen during the Fifty Fifty affair, where most international fans didn't care much about the lies Jeon was telling and the ultrareactionary oldsters running Korean cultural policies and still want the relevant members back performing, which is why I don't think their future won't be too harrowing, despite of the wishes of the Koreans and whatever scheme Jeon and Keena might pull off will go nowhere because they are unlikely to find the Doja Cat like voices which put these nobodies to spotlight.
I have tracked KPop since 2012.
At that time, information on KPop in other countries were scant, and the Japanese media just translated whatever was on the Korean media, or at best let some Korean-Japanese rewrite them in styles the Japanese could understand better.
Similar ways were done in China, so whatever was talked in Korea influenced the growing KPop community a lot, and a toxic residue of these days is that IU, who is still not too relevant outside of Korea, was nevertheless seen as a significant singer in the KPop world because she was running around beating all these famous name in KPop at that time, DBSK, Big bang, SNSD, Kara, 2NE1, B2ast(as they were spelled back then), Super Junior, Shinee, 2AM, 2PM, T-Ara, etc. (Ironically only Taeyeon of SNSD, and Shinee, remain kinda relevnt today other than the culprit).
Older KPop fans relayed whatever was being reported in Korean media, which negatively affected the career of Seo Soojin and Kim Garam, for example. Before the modern days their careers would have ended, but at least Seo Soojin's career is restarting because she is no longer targeting domestic fans. I expect Kim Garam to do something similar in a couple years.
As Bang stated in a recent interview, Korea and KPop are finally separating, after years of a luxurious wagon hitched to an old mule.
However, to make it complete, the ifans will have to stop paying attention to whatever is being talked to Korea.
The major coup was selecting IU as the most listened artist in Youtube Music Korea in 2022, which clearly told the entire world that the Koreans do not give a shit to whatever the world listens to, and will continue their domestic, isolationist way and keep it closed to the world.
The only foreign artist who scored a yearly #1 in Korea was Anne Marie, whose song "2002" was a huge hit in Korea in 2019 (whoever being declared as the winner in that year did worse than her), and she is not exactly a major star as far as the world is concerned; It showed how divergent the Korean tastes are from the world.
The ifans separating themselves with Korean news, Korean charts and whatnot is too little and too late since KPop is already declining, but with them paying less attention to whatever is being said in Korea, maybe it will discourage acts which mostly concentrate in Korea and make them go outside of there (although the biggest culprit of all, having made enough money, will still continue to undermine them domestically).
