She disagreed with the article, saying the dark photons have no energy,
unlike particles.
This is what "she" in the video said about the new theory:

This is a genuinely interesting new way to think about an old
experiment. But I don't think that talking about dark states
of light is going to make quantum physics any less confusing."

That may be so, but if it is valid, it would have to predict
the same as QED for any experiment.

But remember that a theory of physics is a mathematical model

QED has a broader field of applicability than Maxwell,
it predicts some phenomena Maxwell doesn't.
(e.g. photon-electron interactions)

So it is OK to consider light to be a wave according to Maxwell
in some cases. So if you are designing a radio link, Maxwell
is the theory to use,

But there is no way a wave can excite an electron to a higher
energy level, only particles can do that.
QED can predict that a LED will emit light.
Maxwell can't.
