Why was Glamrock Bonnie uniquely targeted and dismantled by Montgomery Gator?

So why was Glamrock Bonnie uniquely targeted and dismantled by Montgomery Gator prior to the events of Security Breach and did the Mimic AI intentionally program Monty's aggression to secure a path of least resistance for Vanny?

Also Fazbear Entertainment officially claimed Glamrock Bonnie was decommissioned due to a series of maintenance issues, but there was the hidden notes and ruined state of his endo in the Ruin DLC that suggests otherwise.

My theory also explores whether this was a coordinated effort by the Mimic AI to eliminate Glamrock Freddy's closest confidant (Bonnie) in order to isolate the group and more easily manipulate the remaining band members.

And finally, once Bonnie was out of the picture, Monty was instantly promoted to the main bass player position on the bandstand.
