People keep forgetting/not knowing he's not CEO and isn't even in the executive board anymore lmao. Or that each group is currently managed by individual divisions. He's a producer only since like 2012, and he is the owner but he himself has said he keeps away from executive decisions because he wanted to focus on the idols and the music more. Sure, he is the owner, and sure he has the final word in some cases when he wants to, i don't doubt it, but he clearly doesn't meddle with most of the executive affairs regardless.
The one thing he did develop after a long time of stepping away from these decisions was the idea of JYP 2.0 which was basically what brought JYP to step on everyone pretty much the last few years sdfhsdfh lmao, basing itself on the experiment that was Twice's self managed division.
Aside from that, some people might see him as creepy (not any different from many male and female solo artists, but due to his age people do judge him more) and ocassionally made boomer comments lmao but i think he is mostly quite admirable above all those things with the way he helped jae or helped jackson's family or rain and his mom back in the day etc etc etc as much as people make it out to be a really hostile but there is a reason why artists kept coming back to him and still hold such a meaningful relationship with him like Sunmi + the other WG + Rain, etc. He gets along very well with his artists and his artists seem extremely comfortable with him as seen over and over in variety.
That + the focus on mental health + his idea of thinking artists should be good people first and foremost + freedom of the artist, etc make me respect him a lot. Even if he wasn't the best person himself, he strives for his artists to be so first and foremost. Plus his solo stuff has been bop after bop since the 90's ngl lmao. So i do think decently highly of him, i do criticize a lot of things but it's still impressive especially for the standards the industry has.
