Have read "Free Software, Free Society" (first edition) by RMS at @fsf. If you are interested in #FreeSoftware then this is a must. Not to worship him, but to understand the core thought of free software.
Why free software matters in this civil society, why GPL and Copyleft are basic concepts of the free software, and how free software and open source software are different? This book answers all of these questions.
