That's why I think the way the term "sovereign" is thrown around is misleading and in fact part of push to transfer more control, and in fine sovereignty, to the EU from member states. People can decide if that's good or bad but the process is misleading.
HN is about curiosity and it seems that commenters do not use any as soon as the EU is mentioned but rather accept the official narrative without questions. The trend is to reduce member states' sovereignty, not to increase it, while the EU is taking over.
