Would it be any better if Qualcomm developed their own proprietary RISC-V cores with proprietary/patented extensions that most software would be reliant on? Currently Qualcomm and ARM are somewhat balancing each other out, with RISC-V if Qualcomm got significantly ahead they'd probably be in a position where it would be impossible for anyone to compete against them (I can't really see any reason for them to make their extensions freely available to their competitors).
