Disclaimer that I'm not an astronomer and might be totally wrong, but from some quick searching, it seems like the article is conflating Hubble's discovery and Riess's. Hubble's law can be true even if the expansion of the universe is slowing down, not speeding up: a galaxy twice as far away as another can be receding at twice the speed, even if that speed is decreasing over time. But it seems like Riess's discovery is that the speed is actually increasing over time. It's related to Hubble's law but not the same thing. Frankly, the fact that I could find that out with 2 minutes of reading Wikipedia reflects pretty poorly on the author.
