The Sokal affair was a physicist attacking the postmodernists for attacking physics (and scientific realism) by showing the postmodernists would publish complete nonsense.
The current attack is saying the physics establishment is backing a theory that doesn't adequately make predictions (not adequately supporting scientific realism).
It can be viewed outside the realm of power, that's a very postmodern view.
