Why are you being obtuse, rather than trying to be clear?
RISC-V is the major Free and Open CPU. RISC-V can run on FPGA. It's natural to want a comparison of this project against RISC-V, especially considering the write-up mentions the less successful OpenRISC project.
This page appears to have been written in summer of 2016. Back then RISC-V didn't even have a stable privileged instruction set yet, so there wasn't really a RISC-V to compare it to in a meaningful sense.
None of this is strange.
