Apart from spying from governments and ad-buzynesses there is also a
risk data leaks. A script might not come from the desired host or there
might be some insider on that side targeting just you, resulting to
potensially senitive leaks (e.g. account info, login password).
One cannot trust a transaction with a web page that has a multitude of
js from outside its own domain.
