To be fair, POWER 10 is an absolute beast. They did make the mistake of using a custom DRAM connection method (in itself actually good), for which there exists only one chip to translate it to normal DDR4. This chip uses someone else's IP for the DRAM controller part. This other company is against the system running with open firmware. Apart from that, they're great.
