So you have this popular, good looking, funny group with a loyal worldwide fanbase and great sales. They are an asset right? You'd be mad to get rid of them?
Let's suppose the financial side was not as important as the Ego of the CEO.
People who think JYP made a mistake have got it all wrong, it went perfectly to plan as he wanted to push out GOT7... WHY YOU MAY ASK??
Because quite simply JYP was jealous of them.
He's trying desperately to be the cool CEO, still releasing music and making MVs, the all singing, all songwriting, all dancing head honcho holding onto his youth forever.
But while he's a successful and talented guy, nothing on the planet will make him cooler and more loved with the female of the species than GOT7 (And he probably saw this internally with how females in JYPE, Twice, trainees, staff etc reacted to him vs GOT7 members).
He sidelined them with half assed comebacks, didn't offer them solo work, cancelled any attempt to write their own songs.
GOT7 had no choice but to leave.
Before all of this was possible he had to make sure the financial impact was minimal. With the emergence of Twice the seeds were planted for the end of Jackson's posse. Before Twice you'd need a boy band in there to bring a solid income to JYP, and that's when GOT7 were of use to him. Then Twice became that 'boy group' from a financial perspective, making more $$$ then he could have ever dreamed of.
But having all your eggs in one basket is never a good idea, so project ITZY was born. Now I'm not saying ITZY was utilised as a weapon against GOT7 but what transpired (and according to ITZY themselves no one in JYP expected this), there emerged an instant hit group. People loved the concept, the idols and the songs and were buying their albums....
Now you had two big girl groups who sold like boy groups, ITZY were the PERFECT replacement for GOT7 from a financial perspective, and a rock solid back up for Twice's money making machine!
Once ITZY started killing it, GOT7 were GONE7... they were no longer required by JYP and he could finally be rid of them.
What do others think makes sense or a load of total bullshit
