Snowden is fake. He was just a a NASA (not NSA) actor. Look at this video: https://www.youtube.com/watch?v=gdgghEZfg7g And ask yourself: why is youtube not finding this video (I had to use bing).
The amazing thing is that way before Linux there was Minix that was also a unix version. But it wasn't open source ( I think the word even existed at that time). I run minix in my computer (I bought it. No torrent, not even internet back then).
