I don't mind so much gov.uk using jQuery, but I noticed recently that the UK government's 'parliamentlive.tv' has a dependency on jQuery loaded from Google's CDN, when there was a Google outage in the country I live in (I think it was something to do with routing on Vodafone's side, rather than an actual Google outage).

I see that's now removed, but Recaptcha is still there. The site works without it, but it seems a bit odd to me that by default, my data is shared by my government with a third party company when I want to participate in democracy online.
