Not entirely, but the process is very slow. RISC-V (and SiFive) caught a moment where it could be used is a way to squeeze ARM on pricing. It doesn't really meaningfully create openness on the interesting parts of the stack (core architecture, SoC architecture, etc.) on its own. In that sense, the hype is overblown. It does _enable_ open-source cores to some degree, but that's it, someone has to take the leap to make a production-ready one. A few companies are trying, but an open-source SoC is even further down the road.
