The gaps on the bottom and the top serve the important purpose of ventilation. It’s a really effective design allowing vertical airflow. So yes, I do prefer air gaps over stinky boxes, and I have personally never seen a creep sticking their head under the gap.









I think this is a very useful license to require in new software procurements commissioned by public entities in the EU. The FSFE calls this “public money – public code” (publiccode.eu). Having a specific EUPL over just the GPL might make this look more proper, even if there aren’t many technical differences. However for personal use I would prefer using good old GPLv3.
