Leveraging a lock-in that doesn't exist any more.
I think these tactics are liable to backfire in a big way. The decline of the desktop has pushed computing towards a much more platform-neutral market. Microsoft has no "killer apps" any more, if they make things inconvenient for people it's just likely to drive them away.
I've been Microsoft-free for almost 5 years now. Granted, I'm a major nerd. I first tried installing Linux in 1999. By 2007 I was using it a maybe half of the time, but always found myself reverting to Windows for something or another. It wasn't until I put an SSD in my laptop in 2012 that I decided to be brave and have a go at being completely Windows-free. I haven't looked back.
My laptop has a legal license for Windows 7, so I could have had the free Windows 10 upgrade in the first year. It would have been a minor nuisance to swap a different HD in and restore the old Win 7 to obtain the upgrade. I thought about it, but just couldn't be bothered. My indifference to the freebie shows just how far things have come. I really couldn't think of any reason I'd ever want to use it.
