RISC-V is an open source chip design. As of today, it’s still worse than x86 (a CISC—“complex instruction set” design) and ARM (a proprietary RISC—“reduced instruction set” design) but if history is any indication, open source will end up overtaking them in the same way that, for instance, 98% of supercomputers today run highly customized versions of Linux.
There’s also some political connotations surrounding it because some countries don’t want high-end chip designs to be available to their perceived competitors (whether for protectionism reasons or military reasons) but it doesn’t matter.
