A. Einstein, "Relativity", Chapter 22: "...the special theory of
relativity cannot claim an unlimited domain of validity; its results
hold only so long as we are able to disregard the influences of
gravitational fields on the phenomena (e.g. of light)."

Einsteinians often worship and repeat this thought but they also want
to develop it. They imagine a celestial body sending light and since
initially the light moves in a gravitational field, its speed varies
with position and an observer would measure it to be less than
c=299792km/s.

It depends on which observer...

The observer is Einstein, ****head. He's the tord that says "us" and includes you.

"In short, let *us* assume that the simple law of the constancy of the velocity of light c (in vacuum) is justifiably believed by the child at school. Who would imagine that this simple law has plunged the conscientiously thoughtful physicist into the greatest intellectual difficulties? Let *us* consider how these difficulties arise."

"The law of the propagation of light in vacuo would then have to be replaced by a more complicated law conformable to the principle of relativity. "

Tough beans, Einstein. The more complicated law conformable to the principle of relativity is w = c-v.


"Prominent theoretical physicists were therefore more inclined to reject the principle of relativity"

Prominent ****heads, more like.
