"OK, since this is physics and not philosophy, can you please show me an experiment that measured the speed of light in our false vacuum and showed that it is below the published value for "c"? Can you also open, say, the standard value of c as published in CODATA and tell me how they were able to obtain that value?

Yes, I can show you an experiment where we slowed light down below light speed with matter. In fact, this is called refraction. Materials have a refractive index that shows how much light is slowed by the medium. Light is never as fast as light in a vacuum, or c, and since there is no true vacuum, that speed does not exist.
Here's how people slowed down light.
