I'm sorry I don't agree in general. There are a number of useful
sites with useful uses of javascript. For instance Gcal. There are
times when it's very useful to share a calendar with a number of
people without setting up your own + an authentication system etc. etc.
When the information is not particularly private anyway gcal still
gives you a range of sharing options.
Other sites that have interesting uses of JS are sites like flickr.
I don't think you can make an argument like their terms and
conditions and privacy policy has a bearing on their use of JS.
I don't find JS makes sites slow in fact quite the opposite. Map
sites fail miserably in speed compared with google maps. Similarly
calendars compared with a good JS calendar implementation. Some of
the JS widgets on flickr do things that would be very difficult
without JS. As for privacy and terms, those are separate issues.
