Another important advantage of RISC-V is academia. RISC-V has much more mindshare/backing from the university researchers, being started in UC Berkeley with big names like David Patterson. OpenPower...not so much. And I strongly believe university research being on top of RISC-V is the biggest advantage in the long term - what that means is that masters and PhD students will be fully trained on RISC-V ISA, and many new architectural research will be already based on the ISA. OpenPower never had, and likely never will have academic backing. Why would a university research choose OpenPower ? The only scenario I can imagine is if they are pursuing a funding from OpenPower companies, but OpenPower is already a small minority in ISA mind-share and market share, and I don't see any chance of them catching up.
