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.

If you think about it there should be a way this works from the
perspective of the inertial frame. Physics should not depend on
frames, even if we are talking about the difference between an
inertial and accelerated frame.

From the point of view of an observer in the inertial frame it is the
dynamic Casimir effect.
