Because 'it's all fun and games until someone loses an iPhone™.'
MSB should work on any system (Mac or PC) that meets the minimum requirements for syncing an iPhone/iPod Touch.
How does it work?
Every time you sync your iPhone or iPod Touch to your computer, iTunes makes a backup of many vital files on your device and stores them in a special folder called 'MobileSync':

If you locate this folder, you will find hundreds, even thousands of confusingly-named files in different formats.

MSB can read your backup and give you access to your data. Whether on a Mac or PC, you can view your data in a single window with an easy, iPhone-like interface.
