I think Wald says that for the inertial observer it appears that
the accelerated detector/thermometer is interacting with the
vacuum and producing the particles around it that provide the
clicks and temperature.
I think the idea that the detector interacts with the vacuum is
misguided. 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.
I think that's right. But it doesn't address how the inertial observer
sees the effects on the accelerated instruments.
