I'm not sure if I'd blame Cre.ker and their ex-management for that, because I think when they were absorbed since they already were managing the Boyz I think that a large percentage of their former staff was directed to manage them. I don't have any proof of this, but I think IST Entertainment is effectively operating de facto as 3 different companies( or they have become so massively incompetent that they might as well be). I suspect there is some sort internal power struggle within IST Entertainment as a result of the mergers and unfortunately their artists are the ones suffering because of it. I don't see any other reason why Apink would continue to renew their contracts up until this year when everyone but Eunji didn't.
IST Entertainment needs to get their shit together because soon they won't have Apink (I don't expect her to renew next time) and Viction is basically disbanded. So, that leaves them with a bloated company managing the Boyz, Weeekly, and ATBO. ATBO got humilitated on national television when they auditioned for Peak Time and were told they weren't talented enough and god knows what's been going on internally with Weeekly. If they don't want to become bankrupt they should stop neglecting Weeekly because other than The Boyz they don't really have any other options other than cleaning up the mess they've made.
