The Actual ARM license and IP, is relatively tiny in overall cost of the chip. It is a very small amount of money for time to market and ecosystem.

ARMv8 ( Specifically the aarch64 part ) is like a clean start. I doubt RISC-V offer any advantage, especially we should now know the uArch is only tiny part of the equation, the implementation matters a lot.

Apart from the fear of lock in or ARM suddenly hike the price 100x, what exactly is the benefits and motives for RISC-V?

Or is this more of NIH Syndrome?

The Risc-V ISA is far more modular and extensible. Also we needed the 128 bit support for our NVM storage research and single address space OS work. No MMU, T-ISA based security, VIVT caches. Other govt projects do have ARM licenses, we chose not to go that way for purely technical reasons. Our lab does have academic collaboration with ARM.
