If you don't believe that photons can cause heating, go stand in
front of an active radar dish.

There are the "oscilltory flow of electrons".

No. The same effect occurs when you put the dish in vacuum.

In vacuum is rare plasma (ions and electrons). Plasma is a conductor.
The electrons are free to move.

If the propagation of electromagnetic waves would be dependent on
residual electrons present in the imperfect vacuum (like in space),
there would be a tendency for propagation to become worse when the vacuum
would be more and more perfect. There is no such effect ever observed.

Up to now we see distant stars. The plasma is produced by stars. So we are
not in perfect vacuum.
My be that such is behind the last star.
