The challenge around issues like this, is that the informal separation between "trusted" and "untrusted" software used to be formalized (by coincidence) as a technical distinction: software you installed to your computer could do whatever it wanted, but you put more thought into whether or not to use it in the first place than you do when you click a link. Now that those cases are combined into a single technical platform, it's difficult to tease them back apart when it comes to level of trust.
