NEORV32 is specifically HDL, and free-of-charge likely refers to getting a free license (BSD 3-clause) to it.
For server/professional market, RISC-V still lacks a selling point. Perhaps something like a pointer masking, memory tagging, or transactional memory in the J and T extensions which are still in very early stages.
