No, it's due to so many intranet applications being written as one-browser hacks completely ignoring standards. Mozilla has had similar issues with intranets (though not to as large an extent, due to their smaller install base), and you can't exactly blame _that_ on lack of standards support. What you _can_ blame it on is things like people writing intranet apps that depend on the user flipping some hidden pref in the browser to relax a security policy and then breaking when that pref is later removed, say.
