That’s funny because the original thermodynamic entropy is defined only for systems in equilibrium.

from who? Clausius?
It doesn't make a lot of sense to me because a system at equilibrium, cannot go undergo any further diffusion, so there's no potential "entropy increase"
Maybe the issue, is that, like an ideal gas, a perfect equilibrium just doesn't occur.
