But, but, it is RISC-V HW... If I don't call the Linux kernel a "Linux
kernel" does that mean I don't have to offer the sources plus my
proprietary extensions to anyone who buys it?

That's understandable.

Yuck.

What? Why no interaction? Does that mean you're currently developing the
GPU in the RSIC-V core without any contact with the RISC-V Foundation?
That's double talk, "We'll open source the core but no one can talk to the
OSS community about it."

I sincerely hope I'm misreading this,
