UniversalVM writes "What is the single biggest issue that bothers open source advocates about proprietary software? It is probably the ability of the vendor to pull stunts like Microsoft's recent stealth software update and subsequent downplaying of any concerns. Their weak explanation seems to be a great exercise in circular logic: 'Had we failed to update the service automatically, users would not have been able to successfully check for updates and, in turn, users would not have had updates installed automatically or received expected notifications.' News.com is reporting that all of the updated files on both XP and Vista appears to be in windows update itself. This is information that was independently uncovered by users and still not released by Microsoft."
