Yeah OP is clearly not fundamentally understanding something about that image

That's why I think c should be called Speed of Causality.

Yes, please go ahead and finish that thought -- it's correct:

Light speed (in a vacuum, of course) is a universal constant.

Have you encountered any counter-examples in a reproducible experiment? Because if you have, you're on your way to a Nobel prize in physics.

(Not sure what your pic has to do with any of that, cuz that sure don't look like a vacuum to me.)

Light speed slowing down is a macroscopic phenomenon. At the quantum level it still is C.
