The point is that the accelerated frame has a different vacuum -- it is not that it interacts with the inertial vacuum, which would tend to suggest that there is only one vacuum. The vacuum is important for the definition of particle states -- different vacua have different definitions of particle states. Hence the vacuum of the accelerated observer is a thermal sea, relative to the quiescent vacuum of the inertial observer.
