"Permissionless development" - want to develop a RISC-V core? Just download one from github or design your own from the freely available specs. No legal agreements to enter or licensing fees to pay. Very different model from Arm (sign a legal agreement before you start and pay for licensing) or x86 (you want a license? LOL) RISC is hardly dead. It more accurate to say it won so comprehensively that it's pervasive. The design principles are now used in every significant chip (including x86).
