Over the last 10 years or so there has definitely been a push by journals more towards word.

I know that for some journals (osapublishing.org, which is optics so engineering/physics) this came at a time when they moved all their content to be accessible as html. I remember reading somewhere (maybe in their style guides) that they said that word allows them to extract the relevant information more easily, so I suspect that MS made some sort of publishing toolchain for this usecase and the publishers lapped it up.

I know that a significant portion of colleagues still prefer to write their documents in latex, and the journals still accept them.
