Your reference is from March 17, 2020, which means that it is grossly outdated.
It doesn't make sense to compare the "crude mortality ratio" (usually called the case fatality rate) for two diseases, because the case fatality rate depends heavily on the proportion of asymptomatic infections and how much testing is taking place. To accurately compare fatality, you need to consider the infection fatality rate, not the case fatality rate. For COVID-19, there are an extremely high number of asymptomatic infections; only about 15% of infections go detected. We now know that the infection fatality rate for COVID-19 is somewhere close to 0.6%, which makes it about 5-10x deadlier than seasonal influenza, although impacts differ by age group.
It also doesn't make sense to say what the R0 for a virus is without context... R0 is not an implicit aspect of the virus; it depends explicitly on population density, control measures, the proportion of the population that is already infected or immune, etc. The entire purpose of lockdown, masking, and all the other control measures was to get the R0 below zero so that infections would decrease. Further, the R0 was probably much higher than was initially suggested because asymptomatic infections were spreading rapidly and went undetected.
