Earlier this year I wrote an interpreter for a niche, proprietary binary format. Someone asked if I could open source it so that they could (more easily) run it on NixOS. I declined as I'm just that strongly opposed to my work being used to train AI models and further entrench the enshittification of the internet.

Curious: So you only release your interpreter as a binary? Is there some license that explicitly forbids use for AI training? (Although it would probably be unclear if that is really enforceable until someone challenges it.)
