> the only winning move is not to play

Presumably no one is forcing the maintainer at gunpoint to have an LLM slightly shake up other people's code, relicense it under an incompatible license and then claim that "every single line of code is written by Claude Code", so I don't see the issue with not playing if that's the only option.

If you can't make contributions that anyone finds interesting enough to include upstream and have no plans to publish your AGPL derived code under a compatible license, you can keep your changes to yourself. Nothing lost, nothing gained, license honored.
