That is "Little Brother" -- prurient neighbour-watching.
Yeah, Little Brother is everywhere. (It's the bigger threat to our culture, IMO).
But this isn't a UK-specific problem. The USA, for example, has Homeowner Associations, which tie neighbourhood-watch curtain-twitching and petty compliance to personal freedoms, property values, paint colour and lawnmowing. The average suburban person in the UK arguably has more freedom from curtain-twitching busybodies than in the USA (where 26% of the population live in an HOA or condo association)
The British police do not have warrantless power to just lazily aggregate Ring doorbell footage or any other such thing (they may have faster access to cloud content with a warrant, but I suspect it is probably still faster to just look at the doorbells in the immediate vicinity and ask permission).
