I didn't claim that Microsoft was unique in anything but the 3E strategy itself.

Actually, what with Google duplicating more and more of Android's core open-source functionality into their proprietary apps and then leaving the open-source code to rot ... Microsoft isn't unique in that way, either.

But more importantly...

That's a long road ahead, since Google has a monopoly on the average user's very mind. And don't forget that Microsoft hasn't lost their stranglehold either, except among programmers and similar personnel. They may be behind on mobile, but they've held onto largely the same markets+marketshares that they had in the late 90's (plus more, though not at monopoly scale, thanks to Azure), and desktops+laptops won't be dying anytime soon.
