I like that question.  :)
It is relativity incarnated to ask such a question.

The answer is as simple as logic herself.  :)

Light travels at [c] *From* source *In* a medium.
This means that the coordinates of the source at the instant of each
event in the wave is the spatial relative anchor from which light
travels at [c] *In* the medium.
This also means that the medium must be Homogenous and Isotropic but
you need to ask why is a medium homogenous and isotropic in the sense
of the force behind homogeneity or the fact that forces seek a state
of equilibrium.

Vacuum is simply a non-materialistic medium and is an electromagnetic
medium in a chaotic state dynamically in equilibrium.

The ideal state of chaos is practically impossible also because the
dynamics of the universe demands a universally compound field at every
spatial coordinate within that universe. However small may that field
vector bias may be and however short may be that duration of such a
bias the net average composes a dynamic background that gets disturbed
by energy fluctuations from electronic transitions in excited
elements.

Each infinitesimal segment in the phase of energy-state-transition is
propagated at [c] due to permeability and permittivity characteristics
of the vacuum. Once the disturbance is created the speed of
propagation is independent from the speed of the source. However, the
speed of the source indeed affects the form of the wave through its
state of motion because adding segments continuously to the phase
depends on the location of the source at the event of that point in
phase of wave creation.

What happens if an atom was vibrating along the axis of propagation at
the same frequency of the orthogonally moving electron that creates
the wave?

What happens to all the waves created in all the directions from a
star like the sun?

They interfere and combine to give all possible combinations of
superposition in all directions.
>From thence on, the radiations begin to interact with whatever fills
the space and gets absorbed, reflected refracted, diffracted,
dispersed, recombined, filtered, and even polarised.

After filtering off the high-energy radiations by the magnetic field
and the atmosphere we receive the lower part of the spectrum through
the natural "low-pass-filter".

That is why we must be sure that the speed of waves is only relative
to the medium of propagation, which is a field of any appropriate type
that can carry the specific fluctuations.

Since the medium contains no specific coordinates to enable us from
making a measurement then it is very reasonable to take the
coordinates of the source at the event of the wave creation as the
origin in the frame of reference, and its state of motion affects the
frequency and the wave shape as well but never the velocity of
propagation.

Kind regards.
