Open does not shuts out commercial and enterprise companies. Providers of RISC-V HW or Designs, like Alibaba, SiFive or Western Digital, do lots of testing too. It would be like saying that Linux does not provides the quality of commercial closed OS (kernel), this is just wrong in multiple ways: 1. Linux is also sold as base of some commercial OS (e.g., RHEL, SUSE) 2. Lots of commercial companies revenue depends directly or indirectly on it, so there's a massive testing effort. In it's sum it so massive that I cannot believe that it's matched by any closed commercial kernel (no actual numbers here, sorry, this is really just personal ball parking). The same can happen to RISC-V, the combined testing effort can easily outnumber the one of ARM in the future. So while yes, testing and verification is not free, it is just not an argument at all against any open CPU design, be it openPOWER, RISC-V, open MIPS, ... Rather, it speaks again for openness as combined test effort will be hard to be matched by a single closed player.
