Well, with many Linux distros being idiot-proof to install and skinning themselves in a way that looks like WinXP, Win7, or OS X combined with WINE getting incrementally better over time, I think that it’s unwise for Microsoft to get too uppity. The main issue with Linux is xenophobia, and that is how Microsoft got the market share they have; people are too scared of new things to expand their horizons and/or too scared of altering their computer from factory condition to even replace Internet Explorer with an actual web browser.
Given the choice between an OS that makes me pay for it by giving away all my personal information and an OS that makes me pay for it by spending an hour to download it, tell it my name, time zone, and language (if you know those three things, you can install most OSs), I think I will go for one that has months-long public testing before declaring their OS “stable” over the one that puts quality, performance, privacy, and security ahead of profit or PR.
Of course, unless you take steps to prevent it, Win7/8/8.1 PCs will download Win10 without the user’s knowledge or consent anyways, so you may be upgrading whether you like it or not. Given the system requirements, you may be replacing your computer outright (again, like it or not) in order to actually run Win10.
That said, Win7 still does what I want and need, so I’m not in a hurry to go to Debian or Mint myself.
