I suppose it's just less likely to be misunderstood among people who 8 months ago had never heard of the concept of "R" (or "the R number", or "c" probably) - especially in a language that people hearing "R" in a sentence will probably hear it as "are" or "our" before "R". I'm much more annoyed by use of "coronavirus" to describe this specific virus.
