In some sense, it doesn't. But the point of these measures is to be anti-racist. To make the environment more welcoming to people of colour. Maybe the majority of people of colour don't care, but I am sure that some do.

In my own experiences, being actively welcoming provides a level of safety that silence will not, because the status quo is that it is not safe for me to be myself, even if I might plausibly be accepted among my specific peer group.

Overall, these are small changes (what github is doing notwithstanding), and the amount of time onlookers have spent whinging about them far exceeds the time spent making the changes.

No, this won't address the most pressing systematic abuses by minorities, but it does make one of the most lucrative careers less actively hostile to them.
