What do you see instead? Aside from a smaller startup that used google-everything every enterprise I've worked with uses MS Office extensively, with a big push to the subscription web version from local installs.
I am encountering it almost not at all. I work in a org that basically doesn't know that Linux exist and outside of top management nobody uses Word. Excel is still massively useful.
Across the 6 companies in the tech space I've worked in over the years (ranging from 500 - 200,000 employees with the median being 10,000) have been GSuite/Google Docs for their word processing need but with various wiki software (most notably confluence) overlapping quite heavily too.
