I looked this up, and sure enough, Ernst Mach was the one who lead the charge (a self proclaimed positivist, which is a position that many scientists would gladly say they support).
Sure enough, it's what I thought - you don't mean that some evil boogeyman named Hegel lead a worldwide charge against physics. (I doubt Hegel even understood physics, lol. But you get my point.)
You mean that two physicists had a disagreement, one held institutional power, and ostracized the other.
Fine, but then why attack philosophy? Things are philosophy until they're not. Dogma happens in every field.
Is it really wrong to blame this one on philosophy? The source of the disagreement was inherently philosophical, lead by a philosopher, backed up by other mainstream philosophers, and undeniably held back physics. I don't mean to imply that philosophy is fundamentally evil or useless even when applied to physics; most early physicists also considered themselves philosophers. I'm just pointing out a mildly interesting pattern that I have noticed while reading about the history of physics. I recall that Einstein credited many of his insights to the field of philosophy. He also famously rejected quantum mechanics due to his philosophical beliefs, which many consider a slight stain on his legacy.
