You see I do understand that they try and I do applaud that. yet on my windows 8 machine I still haven't received IE11, even though I just recently did got a notice that IE has been updated, it is still IE10. To make matters worse even if I visit their website to download IE11 manually [1] they're telling me that I already have IE11.
So that experience alone tells me that not everything is done right yet. And even if everything would work, they have to keep doing things right for some time to regain trust.
IE11 didn't ship for Windows 8.0 it only shipped for Windows 7 and Windows 8.1.
Windows 8.1 is a free upgrade on Windows 8.0, more like a service pack release (when you look at the changes). Why not port it to Windows 8.0, it didn't make sense, 8.0 should fade out as people install the free upgrade that comes via Windows Updates (or the store, I forget which) and is a mandatory update. Opting out of mandatory updates means you opt out of associated upgrades.
This isn't a new or unique policy in Windows, look at iOS, you won't get WebGL on Mobile Safari without iOS 8, OSX doesn't back-port Safari and Andriod has a lot of versions with terrible browsers.
