I have a more crackpot theory. Maybe intelligence is one reason (some revenue there?) but business is a second reason. For years, they depended on a variety of pressures to get people to upgrade to new OS's. First there's the whole office/client/server version dependency graph including CALs and DCs to force businesses to upgrade whole swaths. And of course bug fixes: why fix in a current version when they can tell you it's fixed in future, go buy that? Psychology. Then there's malware. Why would they sit by for around years (McAffe came out in 98!) watching the market get super-saturated with sketchy malware products and ignore security so badly? I think it's the same as above: upgrade now hoping it got fixed in the next new shiny. It's a human flaw. This makes me want to scream to closed source lovers. Why do you put yourself in this position? Open source users can audit and fix it themselves, pay someone to do it, chose another fork, or even discuss flaws openly without getting sued (cough oracle cough). Closed source users have no insight, no transparency, and no recourse but to suffer their abuser.
