His biggest contribution may be the documentation and defining the vocabulary, but when he defines a pattern with a word that has an obvious negative connotation ("anemic"), it feels manipulative.
A while ago I was told by members of a separate team that I was writing the core of my javascript application incorrectly. I was following "functional core, imperative shell"[1] and intentionally separating my data from my functions[2]. Specifically, the code was considered to be wrong because it was "anemic", and I was sent a link straight to that 16 year old page about anemic domain models[3]. The suggestion to fix was to add a bunch of mutable state.
Don't get me wrong - I still almost always appreciate Martin Fowler's writing, as it's often quite good, including the original post. But I also understand some of the skepticism here.
