I am going to be very brief.
can you please explain the economic viability of using free software? how are the developers of free software adequately compensated?
Those two are related questions.
Functional business models around Free software mostly follow a path that involves releasing the software Free (as in freedom and price), and then charging the users for support or services around the core software. Often times, since people need customised variants of software to suit their specific needs, they can (and do) pay developers to work on modifying Free software to suit these requirements. This way, they get what they want without having to build things from scratch, and the software itself benefits as these improvements work their way back into the parent projects.
how big is free software in comparison to proprietary software?
It differs based on what areas you're looking at. At the core levels (the sorts of thing that drive the web: Apache, sendmail, ...), Free software is huge; much bigger than proprietary software. This is also quite true in realms such as high performance scientific computing in research at large universities (where distributions of GNU/Linux, gcc, Free numerical libraries rule the roost). If you were asking about the "desktop space", its installation base is much much smaller than proprietary software, like Windows. But I would be willing to wager it is in the order of magnitude of popularity as Mac OS X.
