NOBODY is forcing you to run Windows on your computer.
While most laptops come pre-installed with Windows you aren't FORCED in any way to keep running Windows - and in any case if you buy a MOBO and build your own type of desktop you'll either have BUY an appropriate OS or use one of the various FREE LINUX distributions.
Ms only became a virtual monopoly for a while because there SIMPLY wasn't any decent competition -- IBM then (far far bigger than the fledgling upstart called Microsoft) had an EXCELLENT OS for PC's known as OS/2 - proper multi-tasking and multi-user - however it just wasn't interested in Home consumers but just wanted the "Corporate market" which actually didn't develop for years later - at that time corporates were using essentially MAINFRAMES and dumb terminals for their networks.
OS/2 would have blown Windows out of the entire universe had it developed properly -- but as we know --"The rest is History" -- big company IBM makes a bad business decision while the upstart Microsoft gets the space all to itself - and what an opportunity that was.

It's perfectly OK to go in for a spot of "Ms Bashing" where appropriate - and on the question of being forced to use the OS isn't one of them.
I don't see though why they couldn't have adopted the W 2012 server route where the "Desktop experience" (Tiles and all) is an install selectable feature. (can also be added afterwards too).
However W8.1 can get rid of most of the annoying W8 stuff.
