First, the authors make a general claim about "most physics textbooks" without providing a single example. I think one will often encounter more nuanced statements in the better and more widely used textbooks.
And I think the paper sorely lacks evidence for the general claim in the concluding sentence: "The idea that physics progress through a series of crisis, is hard to defend." Not only do they present only a single example, but even in that case one could claim that the "crisis" started after the discovery of Planck's formula! After all, it fitted the data supremely well but required this mystery constant: h.
It took physicist a quarter century to resolve the deeper meaning of Planck's constant. If that was not a crisis in physics then I do not know what would qualify as one.
