Yes, I think that it is an easy signal that Microsoft (and GitHub) believes racism and prejudice is worth an adjustment in language. It’s much harder to actually perform systemic changes and I’m sure people would do plenty of gnashing of teeth about any significant movement, such as if Microsoft had grants only available to BIPOC (black/indigenous people of color, who have unique hardships in discriminatory systems in America compared with Indian or East Asian people who have and continue to face discrimination but they do not largely have existing government sanctioned forces to disenfranchise them from their birth to their death.)
