Yes, amazingly I understand that. But it's not any more surprising or funny that the Bank of England would be on HTTP compared to any other policy website which still isn't on HTTPS.
When I see bank + policy + not just some random bank but the BANK OF ENGLAND, I do expect to see HTTPS guaranteeing the integrity of what is unquestionably important and influential data being served to decision makers.
This amused me, but maybe I'm just easily amused.
