Being from an idol show doesn't even guarantee success, and there are multiple recent examples of that. When is the last time you saw an EL7Z UP song topping any charts? You probably don't even know who they are.
And way to miss the point, patty k, which is that fromis_9 left HYBE and got immediately, substantially BETTER results.
They still got the benefit of big resources and a Idol Show to get their name known compared to coming directly from a small company without any benefit from a "Idol show", it's at least is not a disadvantage.
