Exactly why replacing by something simplistic doesn't fly. I'll go on a limb and say if I tried something similar in this guy's field, I would be destroyed for publishing it. And rightly so.
The post in question mostly presents observations about the base line models and data taken from reputable and cited sources. It didn't make up simplistic models on the fly. I would say it is breathless journalism.
I also would wish for better explanations from the scientists actively working on it. My first go to is RKI.
