The regulation not only puts obligations on users. Providers (which can include FOSS developers?) would have to seek approval for AI systems that touch on certain areas (e.g. vocational training), and providers of generative AI are liable to “design the model to prevent it from generating illegal content” and “publishing summaries of copyrighted data used for training”. The devil is in the details, and I’m not so sanguine about it being FOSS-friendly.
