Forced to use your JavaScript libraries in Site.com?

[AnthonyP]

Are we forced to use/include your JavaScript libraries on our Site.com website? If we aren't, can someone explain how I can prevent these from loading: http://screencast.com/t/brD8TaLdqw8M

If we are forced to use those libraries, could you at least update them and minify and pack them? /sfsites/assets/Scripts/jquery/jquery.js?r=1.201211092049180856 is 270KB... plus it's outdated. The current version is 1.8.2 but you're loading 1.5.2

Uncaught TypeError: Cannot read property 'height' of undefined
jQuery JavaScript Library v1.5.2
