If the universe were expanding, the competition between expansion and gravitational attraction would distort cosmic structures (galaxies and galactic clusters) - e.g. fringes only weakly bound by gravity would succumb to expansion and fly away. No distortions are observed, and in a world different from Einstein's schizophrenic world this would mean an unequivocal refutation of the expansion theory. In Einstein's schizophrenic world, any answer to questions equivalent to "Why are there no distortions?" is acceptable. For instance, here an intellect says "Electromagnetic forces is the answer":

Neil deGrasse Tyson clumsily adds "Even the solar system is not expanding", and this is incompatible with "Electromagnetic forces is the answer", but there is no reaction. The problem is solved.

The famous Dr. Becky has also found a simple and straightforward explanation. Gravity is stronger than expansion, Dr. Becky teaches, and that's it. Problem solved (let's move on):

So the lack of distortions should not worry cosmologists, no criticism is coming from anywhere, and yet they behave as if the danger is serious. Cosmologists apply the expansion theory only to gravity-free space. Theoretical descriptions of galaxies and galactic clusters presuppose no expansion:

Sabine Hossenfelder: "The solution of general relativity that describes the expanding universe is a solution on average; it is good only on very large distances. But the solutions that describe galaxies are different - and just don't expand. It's not that galaxies expand unnoticeably, they just don't. The full solution, then, is both stitched together: Expanding space between non-expanding galaxies...It is only somewhere beyond the scales of galaxy clusters that expansion takes over." https://www.forbes.com/sites/startswithabang/2017/07/28/most-things-dont-actually-expand-in-an-expanding-universe/

"Space DOES NOT Expand Everywhere...Is the space inside, say, a galaxy growing but overcome by the gravitational attraction between the stars? The answer is no. Space within any gravitationally bound system is unaffected by the surrounding expansion." https://youtu.be/bUHZ2k9DYHY?t=356

The reason behind the hoax is simple. If theoretical descriptions of galaxies and galactic clusters presupposed expansion, then the competition between expansion and gravitational attraction would have to be analysed quantitatively. And the analysis would not conclude "No distortions anywhere inside galaxies and galactic clusters". And the expansion theory would be unequivocally refuted.

"The universe is expanding, and that expansion stretches light traveling through space in a phenomenon known as cosmological redshift." https://www.nasa.gov/feature/goddard/2019/nasa-s-webb-to-explore-galaxies-from-cosmic-dawn-to-present-day

"As light travels towards us from the distant galaxies, it is stretched over time by the ever expanding space it is travelling through. The longer it travels, the more the wavelengths are increased (reddened)." https://www.wwu.edu/astro101/a101_hubble_redshift.shtml

"Expansion stretches light" is one of the most preposterous cause-effect explanations in the history of science. Why should the expansion of the universe stretch the wavelength of light while failing to stretch anything else? And how can stretching occur if part of space is expanding and the other part is not expanding? Light is stretched as it travels in the space between galactic clusters, then stretching stops as the light enters a cluster, then stretching continues as the light leaves the cluster, etc?

The statement that light is stretched by space expansion, just like Big Brother's 2+2=5, is so preposterous that no rational criticism is possible. The reaction can only be hysterical ("But this is idiotic, don't you see?") and then the critic becomes crank, crackpot, troll, etc.

George Orwell: "In the end the Party would announce that two and two made five, and you would have to believe it. It was inevitable that they should make that claim sooner or later: the logic of their position demanded it. Not merely the validity of experience, but the very existence of external reality, was tacitly denied by their philosophy. The heresy of heresies was common sense. And what was terrifying was not that they would kill you for thinking otherwise, but that they might be right. For, after all, how do we know that two and two make four? Or that the force of gravity works? Or that the past is unchangeable? If both the past and the external world exist only in the mind, and if the mind itself is controllable what then?"

"Why should the expansion of the universe stretch the wavelength of light while failing to stretch anything else?" The expanding universe theory is already "unequivocally refuted" because it is alleged to explain the red shift distance relationship that is observed within galaxies and galactic clusters. This redshift distance relationship is the evidence adduced for the expanding universe. How to describe this inconsistency/contradiction? "The statement that light is stretched by space expansion, just like Big Brother's 2+2=5, is so preposterous that no rational criticism is possible." Expanding space involves reification fallacy. Therefore it is pure nonsense.
