The situation is different. Again, check the number of songwriting credits Soyeon has and compare it to other female idols and girl groups. Compare it to the latest, most successful gg releases and see how it goes: IVE, aespa, Red Velvet, STAYC...
The fact there are other producers credited in (g)i-dle's songs is irrelevant. On a movie set, the director doesn't need to do everything ie. the make-up, the costumes, the movie sets, the soundtrack, etc. to be the director and be credited as such.
