The thing is:
Gaules have always supported them, and with the recent results he started to push the Org, not the players. But we know that his influence power is huge in the Br scene and the fans, so that caused a mass effect of everyone pushing MIBR too, but this time both players and org. So the Org decided to 'make changes' no matter what, as this is what everyone have been asking recently.
kNg is mad about that because they were doing good in NA with decent (but not ideal) results, so for him, Gaules was responsible for causing that, pushing the Org and putting the fans against the Org to make changes.
In my opinion MIBR just did that because of this pressure to show that the Org is bigger than the players representing them.
