You're making the assumption that most of that isn't performative nonsense that in reality doesn't help anything.
Also known as slacktivism.
It got to the point where I would see pronouns and flags and URLs to DEI policies (Click here to stop racism now! Really?) in people's email signatures that I would immediately assume they were insincere and phony.
One person I knew had "LGBTQ Ally" in their professional signature. It's one step removed from writing I HAVE GAY FRIENDS and frankly I found it all really weird, fake, and reminiscent of 1940s Germany where people had to wear their pins to proclaim their allegiance. None of this has place in a professional setting.
