Odd that ARM even bothered to reply. And the arguments are the expected stuff you'd expect to see from an entrenched leader. Basically it's "benefits of standardization trumps openness", though not stated that way.
A few bits struck me as amusing, like the chart with all the extensions to the ARM ISA over the years, most of which have been abandoned in modern cores. Citing the original VFP standard or Jazelle as "innovation" seems laughable.
If I were to write a ARM-vs-RISC-V paper, I'd start with the important things that are actually missing from RISC-V still, like a MMU spec.
