Google, the parent company, may see themselves as a US institution, but they do have subsidiaries in many other countries (including one in the UK). So if their Chinese subsidiary was beholden to Chinese censorship laws, I can't see why their UK subsidiary wouldn't be beholden to the UK snooping laws.
