I understand where folks have the possibility of confusion, how in explaining the value proposition of RISC-V that it would also get explained in terms of Open Source.
RISC-V is an Open Source Open Specification for an ISA that anyone is free to implement however they see fit. RISC-V is Open Source in its model of participation. It is not only free as in beer, but also free in terms of participation.
The USG can prohibit the movement of physical things, but it should not be partaking in the prohibition of the formation or movement of ideas.
