So exactly what browser doesn't Microsoft allow to be run on Windows? Oh yeah, there isn't one.
The crux of the whole argument is just how much Microsoft "owes" other companies (which is, in my opinion, nothing) and their web browsers to be FORCED to be installed on their OS right out of the box ... and the OEM's and system builders, who get massive price discounts for following Microsoft's rules about installing only Microsoft products on the PC. If the OEM and system builders don't like it, they can buy a copy of Windows at FULL PRICE and install it and put Chrome, Opera, or what ever else they want. But as long as they are getting a MASSIVE PRICE BREAK, they have follow the rules of their contract. If anything, the companies that Microsoft is FORCED to put on THEIR operating systems should have to pay Microsoft for all the "free advertising" and "product placement" that they will get by having their browser being installed on Windows.
As far as the end user having a choice of browsers, THEY DO. They always did, and STILL DO.
