Maybe I was being too equivocal. The parent commenters /do/ believe the developer is receiving preferential treatment based on one aspect of their declared identity. And it's not hard to share their sentiment: what warrants a thin Python wrapper library, which does not really bring new capabilities itself, receiving $20k when there are many other projects which could make an even bigger impact with that money? It seems unusual to me. Especially when considering they were choosing from a pool at GitHub scale, which is about as diverse as it gets in the open source software community.
I don't share the belief that "non cishet/white" people are unduly denigrated when they achieve success--not more than any other person on average, anyway. In fact, I see quite the opposite: there's tremendous amounts of pride when "non cishet/white" people achieve success.
