This is to be expected when it appears as if an organization has been surreptitiously undermined by a corporate mole from what had always been a competitor up until said person took over. I've actually seen, firsthand, similar tactics applied to get a company's products used in large companies (i.e. get one of your "moles" hired in a company into a position where they can decree that your product becomes the defacto email/ticketing system/monitoring system/etc, then when they quit and re-join your company you give them a HUGE bonus for a job well done.)

Not saying this is the case here, but it seems suspiciously likely.
