The article begins with "Microsoft appears to be killing off ...", which is quite different than the title here on HN ("Microsoft kills...". The article's original title is also "How Microsoft is killing off..." - which is a bit more honest: this is speculation/analysis. It might be correct, but it's not the same as "Look, we got an official statement from MS saying these brands are now dead" - Sad to see title tweaks for sensationalism on HN, of all places :(
I would've gone for a detailed title too, like __ "How Microsoft is killing off the Zune and Windows Live brands in Windows 8; Live ID to be renamed to Microsoft Account" __ but that would be 118 characters(with spaces) well over title limit(80) at Hacker News.
