For roughly the same reason that the first example of quantum supremacy we attribute to Google rather than individual scientists. I actually know the names of the Chinese responsible, I couldn't tell you the names of anyone on the Google team. I also wonder how the Google result was reported in China. I wouldn't be surprised if it was reported as "Americans have done X".
