Seems like using a copyleft on the reference implementation of a new protocol is a great way to ensure the protocol is never widely adopted.

People who used left-pad deserved everything that happened to them. But, very valid point.

There is no honor system. If your code is open for commercial reuse, that’s it. If you have any expectations that are not in line with that, then yes pick a different license.

I guess I agree with you, I’m just phrasing it from a different perspective.
