> The problem RISC-V faces is that one or more companies start to grow a significant market with non-compliant chips, basically the browser war scenario. The CPU market today is even more closed to competition than web browsers. RISC-V does not "face this problem", this problem already existed before RISC-V. But RISC-V could make this market more competitive. If there is a royalty free standard on top of which all modern CPUs are built (the RISC-V ISA), then a newcomer can easily use it and take advantage of the tools which go with it. But companies remain free to diverge from this standard by adding their own non-standard extensions.
