I find that question uninteresting, because no matter where the fault lies (it's probably somewhere in the middle) the end consequence is that there is no use case where it makes sense for
me to use Word (unless I'm literally held at gunpoint).
I'm either working on a document for myself or with collaborators.
In the first case I'll use markdown for simple things or LaTeX for bigger things since I can work in a familiar environment where I work most efficiently (VSCode).
In the second case, I'll work with collaborators so I will never be able to trust that a document I have sent off for reading is still consistently formatted when I receive it back. This means that any benefits of the collaboration tools (eg. review history or suggesting changes) are wiped off the table. I will have to integrate any suggested changes into my own authoritative version of the document by hand anyways. At that point I may as well work where I fell comfortable and use markdown / latex, and send off Pandoc converted word files for comments by others when it is relevant.
This is of course for serious pieces of writing, not throwaway stuff like eg. meeting notes, but for those Google docs is plenty.
