I'm taking my ball with me !
As per an earlier comment, Microsoft gained market control by encouraging piracy of Win95/8 -- supplying businesses with a CD per desk (which were then frequently dumped en masse) and publishing Microsoft Press guides (aka manuals) to its major products.
Having achieved world domination, they turned the screws with XP activation, coincidentally first forcing businesses to buy broken ME and then broken Vista on new machines and have to pay extra and waste a day to install XP that then needed time consuming Service Packs to work safely.
The nonsense with DOCX as the default save in Word made users who knew no better put pressure on the many who'd stuck with earlier Word versions. Win8 (again) obligatory on new hardware and, if not broken, almost universally unwelcome. Subscription model for applications, costing as much per year as cheapest retail versions cost to buy outright.
Though I'm not part of the market for TechNet or MSDN, I understand how galling Microsoft's strategy (or suicide note ?) is -- in effect, "if you you won't let me win I'm leaving and taking my ball with me".
Well, we can play that game. Follow the mass migration of Joe Public to Android and Apple -- or look seriously at Linux.
