First of all, to take advantage of something, you have to have heard of it in the first place. Some of your younger or more plugged-in friends may have heard of Linux, the poster-penguin for copyleft and free software. They may even have heard of Richard Stallman and the GNU Project. But if you ask a typical non-techie "What's GNU?" be prepared to have him ask if you've got something stuck in your throat. So the first major obstacle to adoption of free software is lack of awareness that it exists.
