@Flaky, I think project policies have many sides, and I don't want to say much about a project that I am alien to but I recognize the risk, yes :-) If I'm completely honest, I don't know what is the best way define AI policy.
In my own projects I purposely don't define any but keep contributors on their toes by zero acceptance to slop. It does not matter to me if someone used AI in the first place but polished the change to be of best possible quality. That always takes time and effort and I'm surgical reviewer :-) I feel that if I would put e.g. AI ban, then that encourages contribute otherwise shitty handmade code. Policies are difficult.
However, we need new trade deals, global agreements, legistlation and stuff like that. This won't happen during Trump administration but hits like this put pressure to make changes post-Trump era.
Right now, only large corps have any protection given that only patented IP has any meaningful enforcing value.
I mean in the beginning cracking games was legal and many other activities that are now illegal. Now a lot of stuff that you can do with AI is by the book legal but morally illegal as ****.
