    Isn’t it possible to add custom instructions and locking others from them, leading back to the current ARM situation?

      The instruction set is a tiny part of the overall CPU architecture. You don’t need to lock it as everything else is proprietary: manufacturing, cores, electric design, etc. Most RISC-V processors today use ARM cores and are subject to ARM licensing.
