I'm not aware of anyone in my circle seeing such agencies as being "nannying". I'm of the opinion that the Food Standards Agency improves life for everyone in the UK. I would rather put up with a little bit of nannying if it means I don't get food poisoning from restaurants.
I used to be all for freedom of speech and anti-censorship, but these days I've seen too many friends and family fall for miss-information. My university-educated brother-in-law believes in all the "5G causes COVID-19" nonsense. He even sent me a video on YouTube from a "Top American Doctor". Sigh.
ps. I think the solution here is to teach more critical thinking in schools.
