> a physicist named Travis Hoppe argued only last year that his analysis of Reddit data disproved the law.

What he disproved was the corollary, that whoever mentions Nazis has lost and ended the argument. People mistakenly refer to that corollary as "Godwin's law", but that's as far as the conflict goes. There is no disagreement about the statistics. Nazi references will happen in a supermajority of moderately large discussions.
