I have a similar but opposite experience. Since around 2015 I've mostly been working with people who primarily use Emacs. In 2014 I was the only weird one, then next team about 3-5, then a dozen, then there was a team of a few dozen where only two were using Vim. On my current team also most of the devs are Emacs users. However, a lot of people use Emacs with Evil-mode, so I guess they can be considered vimmers.
Also, I don't remember the last time when I worked with anyone who writes code and uses Windows.
Anecdotal experiences can lead to a warped understanding of reality; in mine, Windows and non-emacs users are niche.
Don't y'all have a #emacs slack channel or equivalent at your company? I work for a medium-sized tech company and we have a single digit amount of emacs users I feel like. The channel is mostly dead except for a few tips and tricks and the odd time people asking how we each install it on our macbooks.
Anecdotally a lot of managers use Emacs, though that may be an age thing.
(I use emacs for Real Work, unless that Real Work involves a JVM. Still do all the git stuff in emacs/magit, though)
