For me it has nothing to do with being open source or aligned with the "free" philosophy. I don't like IE because it makes my job harder without any real reason.

Why can't it update automatically and save millions of dollars? Developers cost money and companies have to pay tons of unnecessary hours making a web page work on broken IE renderings.

I would not hate IE, and maybe even use it, if it could update itself without needing it's crap Windows Update thingy.
