I've only ever seen it from people in the UK, and I think even then they were NHS employees (they also used a "social justice focused" file hosting service whose name I can't remember, in case you wanted to know such things existed) and not employees of the place I was working at at the time. No unconventional.

That employer was also full of woke politics, diversity quotas, celebrated Floydmas and Juneteenth; so I'm not sure to what extent it correlates with what is now "baseline" levels of corporate wokeness. Perhaps it works as an indicator for the outliers, where if you see them you know you're probably not going to last very long as a normal person.

Hell, our Git repo still has a "master" branch, which I'm silently surprised about. But I work with a bunch of Indians and Chinese, so I guess they haven't gotten around to caring yet. And the company is so paranoid about IT security that no one who would care has access.
