I wouldn't quite say that's the case. Two of the three full Linux capable RISC-V SoC releases this year are using open source CPU cores. The BL808 and the Allwinner D1 both use T-Head CPU cores that are available on GitHub https://github.com/T-head-Semi/openc906 . The JH7110 in the VisionFive2 and Star 64 does use a closed CPU core however.

Look forward to LM4A (Sipeed, Q1). That's C910, even more capable. Far above Cortex-A72. Quite capable.

Not bad at all for an open source core.
