The motion of the observer clearly cannot change the distance between the light pulses

Einstein's relativity from total collapse:
George Orwell: "Crimestop means the faculty of stopping short, as though by instinct, at the threshold of any dangerous thought. It includes the power of not grasping analogies, of failing to perceive logical errors, of misunderstanding the simplest
arguments if they are inimical to Ingsoc, and of being bored or repelled by any train of thought which is capable of leading in a heretical direction. Crimestop, in short, means protective stupidity."
So, in teaching Doppler effect in light, Einsteinians avoid "moving observer" and teach "moving source":
Stephen Hawking, "A Brief History of Time", Chapter 3: "Now imagine a source of light at a constant distance from us, such as a star, emitting waves of light at a constant wavelength. Obviously the wavelength of the waves we receive will be the same as
the wavelength at which they are emitted (the gravitational field of the galaxy will not be large enough to have a significant effect). Suppose now that the source starts moving toward us. When the source emits the next wave crest it will be nearer to us,
so the distance between wave crests will be smaller than when the star was stationary."

Things seem to be Einstein-friendly here. Frequency and wavelength are inversely proportional. Accordingly, the speed of light is gloriously constant.
The problem is that variable (dependent on the speed of the emitter) wavelength of light

contradicts the principle of relativity. By measuring the varying wavelength (or distance between light pulses), inside his spaceship, the emitter would know his speed without looking outside.
For a given emitter, the wavelength of light is CONSTANT. Accordingly, the speed of light is VARIABLE AS PER NEWTON.
