I think there's an element of men always getting more autonomy at that company.
But also it was around DDDD/Forever Young that Blackpink started bringing in ridiculous amounts of money. I'm convinced Forever Young was supposed to have a MV because of the random photobook that came out a few months later not attached to any date or occasion, which was clearly the concept and the styling for that MV. But DDDD was so successful YG didn't need the extra promo.
And that's the difference. Treasure are successful but clearly not as much as YG want/need them to be, so they'll keep pushing them trying to make it happen. I also think YG hates Blinks (the protest truck pioneers) and won't give them anything for free.
