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.
