Contrast may be one root of the technical problem, but claiming a product "ready to launch" while it fails to work for people based on their race (especially when the company clearly didn't put effort into preventing the issue ahead of time) is problematic.

By having a diverse team (or making some effort to include diverse opinions) you'd have a chance to discover new ways to detect faces, or new mitigations to the contrast problem.

But claiming a product is ready for release when it excludes people based on race (no matter the technical reason) is a problem.
