You're operating from the assumption that people own their own code base, and are actually in a position to deal with that migration. It's a nice bubble you live in, but it is a bubble. There is a lot of industry specific software out there that runs on all sorts of odds and ends of versions of stuff. Some critical software for a particular industry I'm aware of, still relies on CentOS 4, for example. It can't cope, and isn't certified to run on anything newer. The end users often find their hands tied, because there's only one vendor producing software that fits their needs, and those vendors rarely give much of a damn about their end users running out of date software that doesn't get any security patches.
