It happens with open source software all the time, why would we expect any different with open source weights.

Because we do. The GPL isn't a suggestion. If you can take open source code and make private software out of it then what are we all doing? No, license requirements and agreement are law for a reason.

Kimi K3 has its own license which is permissive, it isn't at all like GPL https://github.com/MoonshotAI/Kimi-K3/blob/main/LICENSE

GPL is a specific license, it’s not FLOSS as a whole

Because the licenses that apply to software make no sense in the context of LLMs. With the latter, there is no source code to license.

The words of a license are what the license is.
