A number of JavaScript projects have put support messages for the Black Lives Matter movement into the top of their README or home pages. I think it’s an excellent thing, personally.
Autist here. I see this with so much human behaviour. Often the purpose seems not to be actual measurable progress but rather social signalling. I suppose it serves a social purpose, perhaps it is a precursor to material change. I feel it is important to remember that humans are tribal apes. If we deny our nature, it is much harder to overcome.
