The only reason Shannon really got big was because of the topics she talked about, she hopped on ANY sort of bandwagon she could - the only difference was that she was willing to cover dramas that didn't actually need to be dramas. In a sense, the only difference between her and other commentators like Pegasus and Optimus who also make drama surfing content is that CSA had a female voice, was willing to be a moral guardian, and surfed on the wave that is progressivism that helped solidify the acceptance of Cancel Culture.
