Those guys are behind the curve and will soon be scrambling to make sure everything is up to date.
It's the same situation we had with every major revision of Windows in the past. Hordes of people insisting on keeping their outdated, but working and mission critical, systems up and running. Hordes of people slowly finding that they're having to pass on using the most up to date tools for their jobs because they decided to stick with end of life platforms. Hordes of people getting increasingly frustrated as their old infrastructure begins to fail and they're stubbornly insisting they keep on the old and 'working' while it falls apart.
I understand. I didn't want to let go of Windows 2000, what benefit did Windows XP give me beyond a pretty face? But you know, I was wrong then, and they're wrong now. Let's hope they wise up and start taking the steps to migrate successfully instead of waiting until the infrastructure is 15 years old and crumbling at the slightest touch. Those XP guys who come into my repair shop are a sorry bunch, y'know. But the Vista guys are too, and recently the 7 guys are looking pretty down themselves. It will be far too soon that 8 is on the chopping block, but we'll have the same problems with the same people who don't want to ride the curve and prefer to prop up failing systems with bubblegum and toothpicks.
It's just the same old story. It's not Nadella's Microsoft, it's start working on your migration plans and get ready because this happens every five years and it's not going to stop. It comes with the territory. Keep your tools maintained and replaced them as needed, don't hold onto that rusty hatchet that's going to crumble when it hits the wood, that you've already duct taped together. Be better than that at what you're doing.
