Which in practice will mean free to make simplistic implementations using the lessons of twenty years ago.
If this was a winning strategy those open source implementations of SuperH cores would have been incredibly popular instead of dying in obscurity.
SuperH is owned by Hitachi. You cannot use them without a license from Hitachi as far as I know. RISC-V is unique in that its creator permits anyone to make and use RISC-V cores royalty free. It also supports 64-bit, which SuperH never did.
In any case, you should probably stop writing before you shove your foot any deeper into your mouth.

Apology expected.
You should apologize to the people reading your comments for wasting their time. It is clear you are clueless about RISC-V and your foot is well into your mouth.
As for the J2, its creator does not request licensing fees, but Hitachi might require them. Unlike RISC-V, the creator of SuperH (Hitachi) is not known to have declared the ISA to be royalty free. I am not aware of such a declaration and even if there was, it is irrelevant because there is no reason to use SuperH over RISC-V. Nothing about the J2 supports the FUD you are spreading about RISC-V.

You're absolutely out of line.

"FUD". The whole point of the timing of the release of the J2 was it is based purely on now expired Hitachi patents, so they do not require any licensing fees.
Not so simplistic, see the XiangShan HotChips presentation:
