Hopefully you are fine!
This apparent victory in the Newton Wars of the 1730s and 1740s allowed Voltaire's new philosophical identity to solidify. Especially crucial was the way that it allowed Voltaire's outlaw status, which he had never fully repudiated, to be rehabilitated in the public mind as a necessary and heroic defense of philosophical truth against the enemies of error and prejudice.
I am a bit confused about the usage of the word "way" in the aforementioned excerpt. To specify exactly what is irking me, I will frame my question in the following two points:
1: First of all, my understanding is that if "the way" is eliminated from the sentence, it's meaning will remain intact. Is it correct?
2: Secondly, if "way" is really giving the meaning of "method" here, then shouldn't it be "Especially crucial was the way which allowed" ?
