> Do people actually use Word?

I mean, for starters just walk into any law firm.

Especially the junior desks who do the donkey work of turning contract drafting notes from the Seniors into reality. Their entire careers are based around knowing Word templates and macros like the back of your hand. Those dudes probably know more about Word than Microsoft does.

And a whole niche side-industry has established around them, for example people writing software to diff Word files.
