I've always found these loud DEI programs incredibly uncanny - every career website loudly how important diversity and inclusiveness is for them, but in flowery language, as implying they'd actually discriminate against non-diverse hires would be illegal in most places. Which begs the question of the point of these programs, considering of why they were needed this outwards messaging against discrimination, considering it was illegal in the first place.
I've witnessed the DEI transformation from the inside - which amounted to a chief diversity officer being hired, a lot of incredibly sanctimonious online trainings got scheduled for us, and rainbow flags started popping up in the weirdest places.
A few coworkers I had, who checked a lot of the boxes got dragged into interviews and company events (which some found somewhat uncomfortable). Very little changed in practice, and if you didn't care to read the company newsletter (who does that anyway), then you didn't experience much of it.
