Re: What about "extinguish" do you not understand?
I think there's more to it than that. Microsoft has a long history of expansion by acquisition. But all too often, having acquired a product/company they decide to play with it. The product becoming some powerful exec's private football. Instead of keeping the product fresh and useful they'll decide to fix the bits that aren't broken and change or remove any functionality the users might like, while holding on to their own pet ideas against all resistance. Which is why we got Windows 8 and the stupid "charms"- the invisible controls that only ever appeared by accident and when you least wanted them. And they've kept bits of that even in Win 10. Like the very narrow disappearing scroll bars in the Start menu.
