I can’t fully grasp what such licenses really accomplish. Sure, I can’t legally directly take your project’s code and start selling it. I could instead have an LLM quickly scan your code to recreate a derivative of your work without it being exactly your work.
Of course this alone wouldn’t let me quickly recreate something like FUTO as by far the most complicated tech there that they’re not (easily without extracting it from their .apk) publicly exposing is their ML model (that I was literally just writing about What keyboard are you using on android? - #46 by lone-cloud ) that’s used for auto-correcting. I think it would be immensely hard to fine tune a super well functioning model like that and you still couldn’t compete with the big boys like Google’s GBoard.
