This is a strategy tax, for a strategy that stopped being reasonable a decade ago. Numerous alternate browsers have had no problems competing with an "integrated" IE, for many years now. The DOJ case was settled by a completely different set of executives, so the current bunch don't have to pretend that OS integration is somehow vital to the function of a browser. Someone should draft a memo to the browser department: that stupid shit you were supposed to do 15 years ago? stop doing that. An organization that continues with such a farce for so many years is puzzling.
