Don't listen to their music
The best way to show disapproval isn't spewing hate on idols pages, I didn't want sakura to win but adults commenting on a minors instagram is just sad. Instead, not engaging with their content is the best way to show your disapproval, because no engagement is better than hate. They love controversy because at least they get views that way. I thought the music was going to be good because the demos were amazing but they ruin it with their kids bop vibes. The same would have worked with katseye, but instead of not engaging y'all commented hate about gnarly and internet girl and they kept making the same crap because it got hater engagement. So even if you are gonna be a neutral fan, don't listen to something that doesn't genuinely sound good to you as blind support because it'll keep happening.
