I think that's the risk. It's not clear what counts as a commercial interaction. eg I built a lib used for data analysis of bio samples. I have occasionally done some consulting for users, but nothing in over a decade. Does that count as commercial interaction? It's unclear to me. I'm considering deleting the open source and/or updating the license to ban the EU.
Like obviously this is a very low probability risk, but I don't care to take any risks for something that I give away for free :shrug:
Separately, the idea that I have to have a security policy or any other thing; I decline.
