Despite pledging $100M to help Black creators and doing more to, "dismantle systemic racism," YouTube's blocklist upholds systematic racism by blocking racial justice terms, while letting virulently racist terms through.

Brandi Collins-Dexter ( @BrandingBrandi) said this glimpse into how Google manages its platform suggests the company’s investments in building relationships with civil rights communities are “a lot of lip-service.” https://themarkup.org/google-the-giant/2021/04/09/google-blocks-advertisers-from-targeting-black-lives-matter-youtube-videos

Google refused to answer a single question related to its social or racial justice blocks. Rather than unblock terms, YouTube doubled down and blocked terms like, "black excellence" and "antiracism." More here:
