The marginalisation of antirelativists (that is, the disappearance of any real opposition to Einsteinana) has had a natural consequence: Einsteinians don't need to lie constantly and can even tell dangerous truths sometimes. So they explain the Doppler frequency shift (moving observer) by correctly assuming that the wavelength is not affected by the motion of the observer:
Albert Einstein Institute: "Here is an animation of the receiver moving towards the source: (...) By observing the two indicator lights, you can see for yourself that, once more, there is a blue-shift - the pulse frequency measured at the receiver is somewhat higher than the frequency with which the pulses are sent out. This time, THE DISTANCES BETWEEN SUBSEQUENT PULSES ARE NOT AFFECTED, but still there is a frequency shift: As the receiver moves towards each pulse, the time until pulse and receiver meet up is shortened."

Needless to say, if the wavelength remains unchanged, the speed of the light waves relative to the moving observer varies with the speed of the observer, in violation of special relativity.

Then the same Einsteinians inform the world that the Pound-Rebka experiment has in fact confirmed Newton's emission theory of light:
Albert Einstein Institute: "One of the three classical tests for general relativity is the gravitational redshift of light or other forms of electromagnetic radiation. However, in contrast to the other two tests - the gravitational deflection of light and the relativistic perihelion shift -, you do not need general relativity to derive the correct prediction for the gravitational redshift. A combination of Newtonian gravity, a particle theory of light, and the weak equivalence principle (gravitating mass equals inertial mass) suffices. (...) The gravitational redshift was first measured on earth in 1960-65 by Pound, Rebka, and Snider at Harvard University..."

Finally, Einsteinians find it suitable to explain that, even though it is universally taught that the Michelson-Morley experiment has gloriously confirmed the constancy of the speed of light, it has in fact confirmed the variable speed of light predicted by Newton's emission theory of light:
John Norton: "These efforts were long misled by an exaggeration of the importance of one experiment, the Michelson-Morley experiment, even though Einstein later had trouble recalling if he even knew of the experiment prior to his 1905 paper. This one experiment, in isolation, has little force. Its null result happened to be fully compatible with Newton's own emission theory of light. Located in the context of late 19th century electrodynamics when ether-based, wave theories of light predominated, however, it presented a serious problem that exercised the greatest theoretician of the day."
John Norton: "In addition to his work as editor of the Einstein papers in finding source material, Stachel assembled the many small clues that reveal Einstein's serious consideration of an emission theory of light; and he gave us the crucial insight that Einstein regarded the Michelson-Morley experiment as evidence for the principle of relativity, whereas later writers almost universally use it as support for the light postulate of special relativity. Even today, this point needs emphasis. The Michelson-Morley experiment is fully compatible with an emission theory of light that CONTRADICTS THE LIGHT POSTULATE."

Why do Einsteinians both lie and tell the truth? Because that's the way ahah ahah they like it, ahah ahah:
