I did. Apparently you didn't.
“Can we formulate physical laws so that they are valid for all CS [coordinate systems], not only those moving uniformly, but also those moving quite arbitrarily, relative to each other? […] The struggle, so violent in the early days of science, between the views of Ptolemy and Copernicus would then be quite meaningless. Either CS could be used with equal justification. The two sentences: “the sun is at rest and the earth moves” or “the sun moves and the earth is at rest” would simply mean two different conventions concerning two different CS.”

“The relation of the two pictures [geocentricity and heliocentricity] is reduced to a mere coordinate transformation and it is the main tenet of the Einstein theory that any two ways of looking at the world which are related to each other by a coordinate transformation are entirely equivalent from a physical point of view.... Today we cannot say that the Copernican theory is ‘right’ and the Ptolemaic theory ‘wrong’ in any meaningful physical sense.”

Another uninformed relativist. No surprise.
Ah, but the nuances come later. You are aware that there are differences between being locked in an accelerating spaceship, and being in a gravitational field, I’m sure. Similar issues occur with rotating reference frames.
As a practical matter, it takes a lot less energy to rotate an object, than to rotate the entire universe around it.
