People could be lying to you and you would believe them simply because they spoke or wrote to you. I encourage you to read just about any of the FSF's own essays on http://www.gnu.org/philosophy/ or listen to virtually any of their speeches (the Q&A at the end changes with each one). Most of their writings and talks concern software freedom, so you'll learn about what it is and why it matters from almost any of their works. Briefly speaking, software freedom is an ethical concern that people be able to do what comes naturally to do with computers and your friends and neighbors--share and modify software. Free software is a kind of software where one can leverage these freedoms. Non-free software is software where one does not have these freedoms.
